    @ThreeUK Who in their right mind would use 3, the signal is total crap, always has been, one to AVOID!

  • HistorianLaura Laura Brennan MA 💙 (@HistorianLaura) reported

    @ThreeUK is there a glitch in your data signal in Berkshire. Very slow and clunky today

  • Dan_Gardner_ Dan Gardner (@Dan_Gardner_) reported

    @ThreeUKSupport Hi Ali, the work is still ongoing and I'm without a usable data connection during working hours again. It's not really on, there is no warning and my signal just drops (usually mid-meeting). How long is the entire project going on for, not just today's works?

  • CarolineNB Caroline Bridger (@CarolineNB) reported

    @ThreeUK coverage has been terrible for over a week. I know you’re doing work on a mast but how do I find out when it’ll return to normal?

  • Nazi32449355 Nazi (@Nazi32449355) reported

    @ThreeUKSupport I have been with 3 for 8 years and only last year I have been having issues and never got sorted and I am paying £55 and plus add on every 2 or 3 months as my data runs out so quick and Three's never been able to resolve

  • CatMumTiff Tiffany Bates (@CatMumTiff) reported

    Sooooo @ThreeUKSupport are literally the worst. Outage for OVER A WEEK. Missing CRITICAL BUSINESS MEETINGS. Told to DM them, did so. Then told to use chat bot, did so. Now I have to be redirected AGAIN to someone on the phone? I did that last week? And still not fixed?

  • alexrefuses Alexandra S. (@alexrefuses) reported

    @ThreeUKSupport Hi! I’m trying to cancel an add-on. I got a text from Three saying that it’s been cancelled, and then another text about an hour later saying that cancellation has failed.
