  2. HI

  3. I asked for a copy of my bill to be sent to me it was not sent so I called back and was advised it would be with me asap. I then received a bill for one of your other customers which i now have all the details for. Calling 3 really is very difficult due to the language barrier

        1. You said “difficult due to the language barrier” so i was sure you need some specific department.

Please can you comment on this issue, i see you helping a lot of people on your website.

    Many thanks.

  11. Here is what i’m going to send 3:
    Dear 3,

    I have recently taken a pay as you go sim with you and I have unlocked my phone with my previous phone provider however I am still unable to make calls or use Internet outwith wifi, I have put the simple into my phone and the phone shows as “emergency calls only” I have spoken to my previous provider and they have assured me my phone is unlocked and ready for use with other providers and thus the problem may lie with you. Can you assist a.s.a.p as I am now in my contact and have been trying to get this resolved for some time now.

    Kind regards

  12. I have phoned them on numerous occasions,so has my son and my nephew I lost my husband in November notified them to cancel his contract and keep mine on I get cut off my son phoned them about over a couple of days to get my phone back on as I was waiting on a lot of important calls eventually my phone was turned on only to be turned off again we made several more phone calls they cancelled both direct debits for the two contracts the phoned me at 9-15 morning after morning to speak to my husband this has caused a lot of unnecessary stress to me and my family they have been sent the death certificate 3 times and put my phone back on now I get a message saying I’m nearly up to my limit on my phone what limit I think this sort of service is absolutely and have put in a official complaint which I’ve had no reply from

    1. I have had same problem. Advise them that my husband had passed away, sent death certificate which they deny receiving now had letter threatening collection agency. What do you have to do to get these continual phone calls stopped? Won’t hold my breath.

  13. Hi,

    I cancelled my sim only contract instore in July 16, I’ve just found out that they kept my contract open and have placed a default notice on my credit file.

    This is ridiculous as I gave notice and now for the sake of £38, which is 4 months payments I cannot get credit, nobody wrote to me to ask for payment, so I had no idea!

    I’ve paid the £37 just to stop any new default notices, but the defaults still remain on my file!!

    I feel really let down by Three!!

  14. I have tried to contact 3 on my mobile on my home phone regarding nuisance phone calls and there are options to go through which are impossible to speak to anyone. I am going to leave 3 they are a very unhelpful provider. I am also going to pursue a complaint against 3 no one will answer on house phone or mobile and i pay this company a subscription every month. they have to be the worst and most unhelpful phone provider.

  15. Hi, I’ve just signed up for 2 sim only deals, great value-unfortunately 3 sent me an ordinary sized sim not a nano sim. I called your customer service who advised me to take it to my local store and they will exchange it for a nano sim. I called the store to make sure this is correct and they said that’s fine. So I drove 7 miles to our closest store only to be told I have to pay £ for each nano sim. When i questioned this the “store manager” was rude and just kept repeating the amount of £. This is disgusting, all SIM cards are free on every provider-so

    Also the people you choose to be ambassadors for your company in the high street need to be taught grooming and general hygiene, and general customer service skills.

  16. All I have to say is that over the last 6 months they have messed me around merely by the way they do business – you know that way when “they” are looking for something “from” you they are “really” easy to deal with and get a hold of – but when “you” need something from “them” it is a total nightmare of being left on hold and you feel like your talking to a robot with ply one script in their head!!!??? VERY POOR INDEED 3 – I shall speak ill of you if/whenever the subject comes up – NOT GOOD ENOUGH

    1. Totaly agree you cant get proper advice.and i thought 3 network were supposed to be highly rated.can rember my second name when it comes to taking money from account.But have me down as diffrent second name on account.witch i was informed on 4 diffrent occassions would be updated.still have to go through this everytime with them.

  17. Going by reviews im not only one thats been mucked about.and its simple instead of just papping you off with add would be more help to get correct advice.instead of 4 diffrent versions.nightmare when your not on a mobile.but mifi device.

  18. Totaly agree with above comments get it right when its 3 that with customer when looking for correct advice.

  19. Hi Folks,
    Whilst clearing my fathers Garage I have found a mobile phone which appears not to have a charger with it.
    Which one do I need and will I need a battery as well.


  20. Stratford Westfield Store
    I don’t want to think l make a wrong choice choosing 3, seeing many broadband service providers,

    but l was happy cause l believed l got a good deal and a service durable for me and my house- hold interval.

    As l make this request clear while entering into this contract.

    Everyday and myself and my husband just check our e-mails and some times write, it was suggested to us that

    Huawei wireless will be more than enough for us since we don’t use more than what we mentioned, ‘l mean we are not

    using it for business purposes. I was with my husband in Stratford Westfield store. We sign up for this wireless.And for sure, we were

    enjoying it.But 2 weeks after, we couldn’t have access to internet again and we pay a visit to 3 store we were told our data has finished for

    the month, Oh, We can’t believe what we are hearing, because from beginning we laid it out all these that we don’t want to encounter a

    situation where we can not have access to internet when we need it between the space of one month.And we were guaranteed with this service

    by a lady that attended to us.Now we inquired, Can we change to unlimited service,They say it is not possible. we were just somehow as a

    fix.The box has been packed up since last month. And today myself and my husband were in 3 store to discuss way out, how this box can be

    serviceable to us in anyway alternatively. While we were chatting about our experience and displeasure calmly

    with the very Customer service assistant that attended to us the first time and she was explaining things to us. Suddenly a female slimming

    new colleague l hope, join in with us and physically insulted us.We are not

    conversing with her. l had never experienced anything like this anywhere in

    customer service operation, and that so the Manager a very sensible and competent man was forced to pop out and resolve the matter by gently

    listen to our concern, and suggested to put our concern through this medium. Another payment for broadband and it was caped.

    I am looking for a way out to this so that we can enjoy 3 services.

  21. I requested my account closed, wasnt closed and billed. again requested it closed billed again, requested it closed, wasnt closed billed again, I disputed the bills which were then passed to a dept collection agency, whom I had to pay. I made a complaint, 3 apologised and reimbursed my money in full. applied for a mortgage yesterday and was refused due to 3 giving me a bad credit rating. Legal action will follow.

  22. I need to speak to an operative to sort my phones out
    in lockdown alone cannot type painin my hands
    Is the a call me service
    chat rooms cant speak promised they would get you to call week ago
    must have verbal coms with person who can correct my accounts 2 phones
