    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 @virginmedia @o2, spoke to one team member who cancelled my contract, at least I think he did as I had the same conversation last summer and payments have still been coming out of my bank! Transferred to "customer service" who strangely could not hear me to deal with my complaint 🤔

    @O2 @virginmedia @o2 #contact if your customer service team can not hear their calls how do complaints get resolved? No email address to complain to, do I have to write in? Should I just proceed direct to small claims court?

  • ICrazy1RU2 June Shannon (@ICrazy1RU2) reported

  • SangeetaKhurana Sangeeta (@SangeetaKhurana) reported

    @SkyHelpTeam It’s a mobile network issue as I explained above as @o2 have advised! That’s a total now of 7 days without being able to use our data which I am paying for!!

  • ICrazy1RU2 June Shannon (@ICrazy1RU2) reported

    @O2 #awful reading other messages I can see that my bad experience with O2 is not an isolated incident. Long wait, pretend not to hear so they can hang up without dealing with complaint.
