  • stephenblevins9 Stephen Blevins (@stephenblevins9) reported from Rich Hill, Northern Ireland

    Could someone at @O2 explain why the service in BT61 has been diabolical for almost two weeks? Bit of a nerve advising us of a spike in bills alongside a drop in service? Not exactly sure what I’m paying for at the minute.

    @O2 new phone, transferred sim. 6 days later still no working phone, no return call from CS, abrupt rude lady on phone no help, O2 colleagues tried to help but not much knowledge. Big up Ahmed Clifton O2, only one to apologise & really try but still no phone. Appalling Service.

  • yilank yilank™ (@yilank) reported

    @O2 (3) Unfortunately, we did not know that this was the case and it was our first service purchase from"O2". From now on, stop getting service, nd when you see the "O2" text,stay away from this company.We made a big mistake by getting service from"O2",so don't make the same mistake.

  • k_ravenhill Ashleigh K👑 (@k_ravenhill) reported

    @O2 not taking my 5th call to report fraud seriously … been waiting for a call back for 2 months now and I’m still getting threatening letters … sort your **** out!

  • ArranKenny Arran Kenny (@ArranKenny) reported

    @O2 can’t get through to cancel my Apple Watch data plan. Phone rang for 37 minutes before I hung up… shouldn’t be this hard to cancel a contract

  • JayChes1 Jay Ches (@JayChes1) reported

    @O2 28 minutes to pick up the phone then hang !! You send default letters for bills that have been paid !!! You increase my airtime plan without any notice !!! For a company your size you are absolutely diabolical my next step unless you contact me is to go to the ombudsman !!!

  • yilank yilank™ (@yilank) reported

    @O2 (1) I have never seen a company as bad as "O2" in my life. CUSTOMER SERVICE Terrible. They are making fun of the customer, even the customer service representative we called before Christmas was drunk.

  • NathalieBayley Nathalie Bayley (@NathalieBayley) reported

    @O2 struggling to get through to your customer services, been on hold for over an hour??

  • SCDave86 Dave T (@SCDave86) reported

    @O2 Having an absolute nightmare trying to bring my number over from another network. The online form is asking for the password I'd use to contact customer services, not to into the site with? I've only ever chosen one password.

  • em_burnie em burnie (@em_burnie) reported

    @O2 I'm trying to unlock an old phone that I had with you to use my current sim as I've broken my phone, and whichever way I try I can't contact anyone because I'm not a current customer and don't have access to a phone

  • nmhrbrtsn Niamh (@nmhrbrtsn) reported

    @O2 I ordered a new phone and contract this afternoon and now on my current hand set I’ve had NO service for hours and I cannot ge through to any customer service reps? Will I get my service back? Need this phone to function tomorrow before new one arrives!
