    @ThreeUKSupport No, if you look at the whole thread, this is just a list of how awful your mobile data service is. Apologies. This was from last Sunday.

    @ThreeUK please can you have a member of senior management contact me. Having no joy with the current people. Diabolical service

  • itittatwifey Emma 💜 (@itittatwifey) reported

    @ThreeUKSupport Hello, just spent 30 mins on live chat and no help whatsoever given with the issue of the auto renewal not working. Can someone help me please.

  • bkpatel81 BHARATKUMAR (@bkpatel81) reported

    @ThreeUK Renewed contract not started but you cannot cancel ? I went into store, called customer care. NO HELP AT ALL. I am not happy with service. I have fill complaint form. Please do needful. How come there is no grace period to cancel order ? No return policy 🙁 ?

  • MaundBromford AJJM (@MaundBromford) reported

    @ThreeUKSupport Great - but there is no local store. It would have been good if the replacement SIM wasn't cancelled due to a technical fault? And why try and upsell to an unhappy customer and then put them through to customer services and not respond. Rubbish service!

  • StratCars 🇺🇦 sɹɐƆʇɐɹʇS Esq.🇺🇦 (@StratCars) reported

    @ThreeUKSupport Hi. Seem to be having issues with data and calls in the B15 area of Birmingham for the past few hours. Is this a known problem ?

  • BVickers25 Bradley (@BVickers25) reported

    @ThreeUKSupport I can not take a phone call in my own house because the service you provide is awful. I live in an M9 postcode. I have "2 bars" of signal. This is an ongoing issue.

  • itittatwifey Emma 💜 (@itittatwifey) reported

    @ThreeUKSupport I did the live chat this morning and they didn't help. It was 2o minutes and no solution

  • XantheClay Xanthe Clay (@XantheClay) reported

    @ThreeUKSupport you asked me to get in touch when I had no internet despite having plenty of signal. It’s happening all the time but usually because I have no internet I can’t get in contact. But right now in BS6 I can get three “bars” of 4G but no internet. I’m on wifi now.
