    I've been a Three mobile customer for 4 years and for 3 years I used to have unlimited data, this year I went to the shop and the guy told me to change it for 17 G instead keeping the unlimited contract. That's fine! It's cheaper and my average is 12G per month. However since there it becames a nightmare!!! EXTREMELY SLOW internet, internet goes out all the time... so annoying! Another thing on the day that i changed my contract they told me buy this and that and we will give you a £150 voucher for amazon. I was happy with that. £150 voucher who does't like it?? however when i checked it online they say the voucher will be redeemed after first payment (no problem) and then amazon could take 2 to 3 month to send the voucher...this was in August 2016 5 months passed and nothing!!! I wrote a complain to three and they ignored me!!! Very disappointed!!! I pay every month £55 for an useless service!!!!! Can't wait for next August to finish my contract.

    I got a 300 minutes + 3000 texts + 12GB data to which cost me GBP20.

    My problem are :
    1. There are too much slower of data connection
    2. There are too ofter 'disconnect' issue during surfing online
    3. There are too much often 'NO SERVICE'.

    It's not good to complaint, besides its not type of people who like to do so but all I can say here is.. I made a mistake when I thought that UK has its all the most highly quality both of services and performance. It's so embarrassing when I realise that is just wast't true at all

    This is would be the first, and the last I'd use this ISP.
    The most worst ISP that I would not recommended it to other service user.

    Never have I experienced such appalling customer service, misinformation and zero value for loyal customers. As a whole Three is one of the worst broadband networks out there. They overcharge extensively even though they reassure you the data usage is capped and do not notify when this changes. Resulting in paying hundreds of pounds extra from what you expected to pay. Putting customers at a loss at their gain. If you're thinking of joining 3 and do in the future incure a problem please expect: long telephone calls, repeating yourself to multiple call handlers, with the end result being a waste of your time and money. Completely unprofessional.

    I wish there were 0 stars but unfortunately, I can rate minimum 1 star. I used this operator from January, and I am from overseas, when I asked them if I will or will not pay for when I am not here they said there will be no problem, you will be paying pay as you go, but then gave me monthly, so I had to pay all year even the 4 months which I was not in the UK. When I told them that they said it is not their problem, I have to go to the store where I bought it. Afterwards, this month they did not give me my new bill, so my usage this month added up to last month bill, so I had pay 30 pounds extra. Anyways, maybe it is cheap but the worst customer service and telephone operator I have ever seen.

    I decided to join three mobile and get a contract SIM. Worst thing I could have possibly done. The first 6 months was meant to be half price. £11.50! But, they charged me that PLUS the full amount. They admitted to charging me too much and would not refund me. So, therefore, I cancelled the contract SIM. They are now threatening me with an outstanding balance of £213!! For cancelling. Threatening to take me to court etc. Keep sending letters, emails, you name it. I don't believe I should pay this money as my actual mobile did not come from three it was just the SIM card and they are expecting me to pay this for their mistake. Just don't go with three it's the worst and they do this to everyone and the signal with them are rubbish anyway I'd recommend going with something like virgin network rather than three.

    I had contract with 3 uk for last 10 months was slow i rang up soo many times to solve this issue however, it was always ended up "making so many excuse and not taking it seriously so i got feed up from keep calling at them!
    At the end up 10th month i got £40 extra charge than normal i rang up the excuse was that i have used extra data even though from beginning i was allowed to use (all you can eat data) so i remind the person i was on the phone to he sayed sorry we won't charge you extra anymore and will not going to charge you for next month payment so i waited one more month on the start of next month again this happened i have been charged even 50 extra this time so i have cancelled the contract! Unfortunately i ended up with losing over 100 pounds and 50 for the cancellation policy. This is how they treating their customers! I have made a complaint for refund but nothing has been done since last month. Please please reconsider if you getting pay as you go or contract with 3 as i swear to god you will regret it. As all they want is ur money bland not giving you anything back!

    I'm so sick of them, leaving after being a long time customer.

    They refuse to help me, and I've had numerous emails with rude and arrogant staff. They've doubled their prices on some contracts, and I'm not prepared to pay it.

    Clearly Three don't give a damn about their customers, and people seem to be leaving like rats off a sinking ship. Personally I'm glad to be rid of them, and don't recommend them to anyone at all.
