    @ThreeUK What the hell is going on ? No voice service all day ! I hope this is reflected in our next bill #Shambles

  • Calummoore96 Calum (@Calummoore96) reported

    @ThreeUK How long is it expected to stay down for? It’s been all day and I have phone calls to make!

  • Trekkygeek Timmo 🖖🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@Trekkygeek) reported

    @Cliffinkent @ThreeUK @VodafoneUK LOL. Yeah, you make a good point. They're all as bad as each other really.

  • VanessaWelham1 Vanessa Welham (@VanessaWelham1) reported

    How can @ThreeUK network be down all day! Any idea when this will be up & running. Out of contract now, & genuinely tempted not to renew. This is bad..

  • NathanB30426880 Nathan (@NathanB30426880) reported

    Anyone else @ThreeUK down?? I can’t make or receive calls?

  • markisone1 markisone (@markisone1) reported

    @ThreeUK Data service also not working in Aberdeen

  • CryptoMK2 CryptoMK (@CryptoMK2) reported

    @ThreeUK Given how shoddy this service is and service not up to standard, we should all be able to break the contract and go with someone else. I have better reception in a remote part of Africa.

  • Trekkygeek Timmo 🖖🏴󠁧󠁢󠁷󠁬󠁳󠁿 (@Trekkygeek) reported

    @HalaMadridz0 @ThreeUK @skytv It was a gesture none the less, and not all of us use dodgy sticks. I for one was grateful not only for the free movie but also the emails I received apologizing for the outage. **** happens but it's how the issues are dealt with that leave an impression.

  • DanielB8008 Dan (@DanielB8008) reported

    @ThreeUK Are you going to fix it anytime today, it's shocking a service goes down and it takes you this long to resolve it
