    @ThreeUKSupport Read the above. The issue was not a technical issue our side but a problem your side which you don't seem to be prioritising. What more can I do to get you to take action and look deeper into this matter?? If you cannot do this then let her cancel without charging the exit fee!

  • moproblems44 Momo (@moproblems44) reported

    @ThreeUK when is the mobile internet going to be up and running again? It's been 2 days now of no service.

  • mrskishere Lorna K (@mrskishere) reported from Stirling, Scotland

    .@ThreeUKSupport why do we have a very intermittent phone signal at FK7 9HU. It’s always terrible and weak but today 1 bar or no signal all day.

  • crouchendmum1 Muswell Hill Mum (@crouchendmum1) reported

    @ThreeUK cant make calls in Jersey. 40min with your customer service team who are asking if they can contact me in 72 hours but that time I will be back in London!!!! So bad!

  • pickled_tinker Grody (@pickled_tinker) reported

    Also, what option do I use on your pathetic customer services number. I hit 4 for other and the 4 options are friggen useless. Seriously, @ThreeUK have you taken onboard the scum baggery of O2, because if you have, god help you.

  • irdawson Ian Robert Dawson (@irdawson) reported

    @ThreeUKSupport Thanks for the update, Ali. Is there a timeframe for a fix? Hours? Days? I imagine I’m not the only one struggling with working from home.

  • SignaLtd Signa (@SignaLtd) reported

    @ThreeUKSupport When did this particular issue start please?

  • RyanRafferty96 Ryan Raff 🇵🇸⭐⭐ (@RyanRafferty96) reported

    @ThreeUKSupport had no mobile signal for 2 days now. Website says you're fixing a problem in my area but my mum isn't having any issues on three and she lives in the same house. What's going on?

  • GraCarr Graham Carr (@GraCarr) reported

    @ThreeUKSupport Hello, I just wanted to say that we are now in day three of having no internet at home. Is there any real update for the South Devon area or a possible estimated time to resolution?

  • Appliance_Test London Appliance Testing (@Appliance_Test) reported

    @Kourdoullou @ThreeUKSupport Their customer service can't give a date 10 days now and they still don't know So how do the Twitter team know a date or are they just throwing out a random date to try and shut us up
