    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 your customer support/ virtual assistant is untrustworthy, impolite unprofessional and rude. We were hung up on last night and your assistant just now answered his call not by introducing himself or mentioning the brand just a ****** sounding “hullo”. I am trying to sort 🧵

    @O2 I have been trying to get hold of the Customer services Dept but I have been on hold for over 2 hours !! Online chat is not working either !

  • NqaguM Nqagu Mabena (@NqaguM) reported

    @O2 I have complained of not having no network or reception on my mobile for over 3 months when I was in Upper Heyford. But you were taking money from my account, for services not supplied. That was over £190. Now you have cut my mobile off.

  • Bad_Gamer_Glenn Glenn (@Bad_Gamer_Glenn) reported

    @O2 what has my wife got to do, to actually get through to someone in payment management?? Been trying for 3 days , she either gets cut off or given a number to ring by customer services, when she rings the number, it ends up being someone who doesn’t work at O2.
