  • ojtravel OJ (@ojtravel) reported

    @O2 I did it on Wednesday last week but it didn't work. Called customer services on Friday and they said they'd sort it. I have restarted my phone about 10 times with the new SIM in it.

  • TommyDoherty Tommy Doherty (@TommyDoherty) reported

    Hey @O2 can you please stop asking your various international call centres calling me from random UK and mobile numbers to ask me if I want to be your customer? Also when I say I am happy where I am they are rude and hang up!

  • FlipzBrockTown remz (@FlipzBrockTown) reported

    i can't believe @O2 don't care about their customers to such a degree. loyalty really don't mean nothing to them. over 15 years! i'm ready to move. 9+ days just to raise a complaint. 5+ days for insurance which is 24hrs lol! ridiculous and unacceptable. the attitude as well kmt!

    @virginmedia So in the meantime NOBODY is able to discuss how I leave the contract I have with you that IS NOT BEING FULFILLED - I wonder if @o2 or @ThreeUKsupport will be happy to take my business. I cannot see any issues on their sites like on your forums.

    @kayleighannalei @tescomobile It'll be @O2 shockingly slow data

  • AlReid31064729 Al Reid (@AlReid31064729) reported

    @O2 I’m also on o2 - why at times have I been able to get signal there when she hasn’t?

  • ___kw98___ kayla (@___kw98___) reported

    @O2 customer service is dreadful

  • HaymanMatt Matt Hayman (@HaymanMatt) reported

    Been an @O2 customer for almost 20 years and its time to change. Phone signal and Internet always seems to be poor in the places I regularly visit, even though my phone is showing 4/5G. @EE, what deals can you offer a new customer?
