    @ThreeUK @ChelseaFCW I'd like to start 2023 off with a working phone but despite being flagged to other services as a vulnerable customer due to my disabled daughter three aren't prepared to make any effort to investigate a lack of service. Maybe look closer to home for some excellence 3.

  • sunsamuel341 Samuel Sun (@sunsamuel341) reported

    Your network is non-existence since Christmas and I live in downtown Edinburgh. Customer Service does not help, refused the option of termination of the contract, stealing my money. At this point it’s an offense @ThreeUKSupport

  • BrettOfKent Brett 🇩🇪🇬🇧 (@BrettOfKent) reported

    Well... 4g doesn't work on @ThreeUKSupport.. Put it on 3g an presto! Notifications!!

  • angelicbeing kathy duffield/ (@angelicbeing) reported

    @ThreeUKSupport internet and phone service completely went yesterday and it’s gone off a few times already . what’s going on ???

  • utomi_victor Victor Utomi (@utomi_victor) reported

    @ThreeUK... Never tot that I will walk away from this network provider. Your services have been abysmally poor and distant to your customers How is it possible that a customers lost phone, cannot be reissued with a new Sim after 8days?? My Nos 07588115678😲

  • lyns24 Lynsey (@lyns24) reported

    @ThreeUKSupport I have reached out to them ALL WEEK! I’ve paid for a phone and not received it. THREE should be reaching out to them, not me I’m the customer. I can’t seem to get your call centre staff to understand what’s happened.

  • Fragmentsoflife Vic (@Fragmentsoflife) reported

    @ThreeUK for the past week I cannot use any data, every site / app says I have no connection regardless of how strong my 5G signal is. Help please?

  • NicolateGwati Nicolate Gwati (@NicolateGwati) reported

    @ThreeUKSupport I moved my number from my previous network to 3 but l seem to somehow have two numbers in operation, one which is my number that was moved from the previous network and the three number that I was given. I also can’t get into my 3 account because of this

  • kemik Sean (@kemik) reported

    @ThreeUKSupport Can I sign up for a contract via your website if I'm already a 3 customer, and then move my old 3 number to that new SIM?

  • slainealex Alex (@slainealex) reported

    @ThreeUKSupport Why can’t I login into my account either via email or app? Constantly being told ‘something has gone wrong’ & to ‘try again later’. V frustrating.
