    @ThreeUKSupport So now I am having to go through a credit card dispute as your customer advisors are unable to help me further.

  • estefanialed Estefania Led (@estefanialed) reported

    @ThreeUKSupport Tuesday will be 10 days without signal. Is that the best you can do? Webchat is useless.

  • leoncrabtree_16 leon clare (@leoncrabtree_16) reported

    @ThreeUKSupport Or you could tell me how you’d help now. And fix it ?

  • StuartDavies Stuart Davies 🇪🇺 (@StuartDavies) reported

    @ThreeUKSupport Will do. There’s been scheduled maintenance on a local mast for the last few weekends, but issues seem to be continuing.

  • ryankaye Ryan Kaye (@ryankaye) reported

    @ThreeUKSupport Not that I can see and even if there was surely hiding additional costs in small print isn’t really in the spirit of good customer relations. Particularly as I’ve been a customer for about 10 years.

  • lukeflegg Luke Flegg (@lukeflegg) reported

    @ThreeUKSupport Thanks for your reply Kirsty. I don't see that text. I also have not been able to return to the UK because the UK entered Tier 5 with strict border restrictions, but I am assured my flight day after tomorrow will be operating. I need a phone to get home, for my safety. Help!

  • Ledgicm8 Sam Girvan (@Ledgicm8) reported

    @ThreeUKSupport Ah, I found it. I can confirm 3G is working for me. Hopefully the fix is completed soon. Thanks for the help.

  • leoncrabtree_16 leon clare (@leoncrabtree_16) reported

    @ThreeUKSupport Just changed my Sim only contract to a new £17 monthly deal, however I’ve just received a letter saying the bill is £32 monthly with a £10 deduction. Can you please fix this... what SIM only deal costs £32 ???

  • klmoorex_ Karen M (@klmoorex_) reported

    @ThreeUKSupport any update on the ongoing mast issue in the TR7 area?!

  • ZosieJenks Zosie Jenks (@ZosieJenks) reported

    @ThreeUKSupport I was just on the chat with you and you said you can’t cancel the account and give me the refund through the webchat so I should call the cancellation team, who also weren’t able to access my account. So literally no one from your team is able to give me my money back
