    Quite shoddy of @O2 to refuse me a contract as a new resident of Northern Ireland when my driving licence is in the Republic of Ireland and not offer an alternative verification or reply to my email of complaint from 6 days ago.

    @O2 Signal keeps going down and calls cut off all the time, also the volume is at the highest setting and it rings loudly ones then goes straight to quite. once on the phone I can hardly hear the person on the other end unless I have them on speaker or earphones in 😩

    @O2 No problem, I would have liked to have been able to tell you the guys name as a shout out but he was really helpful all the same.

  • DanielMc95 daniel mccluskey (@DanielMc95) reported

    @O2 why is it that when you upgrade you cant get hold of anybody to help! But leading up to your upgrade they hound you!

  • hrgwill Harry Gwilliam (@hrgwill) reported

    @O2 the worst provider/ company I have ever had to deal with. Customer service is pathetic.

  • Joellemsvr Joëy (@Joellemsvr) reported
