    Is Three down? @ThreeUK

  • tpaulmorris Paul Morris (@tpaulmorris) reported

    I feel very let down by @ThreeUK and have no choice to cancel this contract forthwith. Perhaps if your sales team were less eager to sell a product and more open with the restrictions on the use these sorts of situations would not occur?

    @ThreeUKSupport hello, would it be possible to get a copy of my final bill please? I have just left three and ported my number out. I received a sms to say my final ebill was ready to view, but I can’t login to view it as my number no longer works on the three site or app. Thanks

    @ThreeUKSupport G22 7DF ? Glasgow area, it worked for a few minutes there but seems to have gone down again. I am assuming there may be some network maintenance ?

    @Cassidyy86 @Ashby94CFC @ThreeUK They used to be the best but gone down rapidly in the last 6 months. The signal now is absolute pants apparently it’s down to overcrowding and that’s from members of their staff.
