    @O2 your O2 Priority app isn’t finding location accurately at the moment. So cannot access local offers. It seems to randomly select a different location each time I open the app. Can you fix this please?

    @O2 easily the worse network in the UK. It’s more likely for me to not have signal than it is to have it.

  • PUSB Stephen A (@PUSB) reported

    A new low for customer service @O2 when trying to move from Vodafone but after 3 hours on the phone, email links not working, cut off twice and not called back when said they would I don’t think I will bother. Appalling

  • oatesie76 Colette Oates (@oatesie76) reported

    @O2 I was giving your customer services department a chance after all the negative comments .... but I literally give up .... a replacement SIM must be the easiest query to deal with !!!!

  • KellyFriendPR Kelly Friend (@KellyFriendPR) reported

    Hi @O2, your service checker says a mast is down in the Southampton area. Any idea when it will be back up please?

  • AmitP327 AmitP (@AmitP327) reported

    Word to the wise : @O2 WILL NEVER contact you to convince you to move your near ending phone plan to a new fancy "business" plan, never, ever. Be aware of companies pretending to be you service provider. Remember : O2 don't do cold calling. Pass the word 📣

    @O2 I’ve been trying to get help but if the experience I’ve had from the call Centre in the last 24 hours is what O2 customers get then it doesn’t bode well. If you want to contact me on 07837 340241 then I’ll talk it through but I’m not calling again.
