    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.

  • dartduignan180 sean duignan (@dartduignan180) reported from Culmore, Northern Ireland

    @O2 @TweetingChop Your network tips are your way of fobbing off customers...... is there a timescale to repair ****** masts and services? Can we complain to Ofcom or someone to get action?

    @O2 Hi awaiting a delivery of new phone. My02 can't help. I have been waiting g all day. Still no sign. Said it would be today?

  • ianpegg Ian Pegg (@ianpegg) reported

    Hi @O2 I am a new customer - at what point do I need to activate my new SIM - after my phone number port has completed, presumably?

  • mwildsmith1989 Matthew Wildsmith (@mwildsmith1989) reported

    @O2 Your staff in the @OxfordStreetW1 store have severe attitude problems and appalling manners. Maybe give the jobs to people who actually want to be there.

  • ianpegg Ian Pegg (@ianpegg) reported

    @O2 Ah, okay! I've already requested the port and received confirmation it will happen tomorrow. As I understand it then, I won't need to do a SIM swap at all? Will my Vodafone service automatically be cancelled once the number has ported?
