    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.

  • oharama Marian O'Hara (@oharama) reported from Derry, Northern Ireland

    @o2 Your customer service system is horrendous. I need to speak with someone urgently re. my bill! Why do you just cut my call off every time I try to go through the process??

  • Sheikspeare9 AS (@Sheikspeare9) reported

    @O2 so not only do you fail to respond to calls and tweets you send me an invitation to send a direct message and then you completely ignore that too.

  • repoRkraM Mark Roper (@repoRkraM) reported

    @O2 hi - I started a SIM swap on Tuesday evening and it still doesn't seem to have completed - much more than 24 hrs. Is there a general go slow or a specific problem with mine?

  • lisa_manger lisa Manger (@lisa_manger) reported

  • suzannesafc suzie (@suzannesafc) reported

    @O2 hi i recently signed up for a new contract 10th October the lady in the store put my email address down wrong how do i access my account please

  • DieselDragonUK DieselDragon (@DieselDragonUK) reported

    @Amalik7991 @O2 EE (BT) gets better coverage as they’re the only network to hold two of the four GSM licenses issued by @Ofcom. Having one each of 900MHz (Orange) & 1,8GHz (121, later T-Mobile) they have a *huge* chunk of spectrum versus any other operator, hence the reliability. 📶🎂😳

  • STXMFORD chris (@STXMFORD) reported

    @O2 i keep going to fill in a keep my number form but i get emails back telling me that it could not be completed and i can never get through to anyone when i call customer service

  • Laurad1989 Laura Dargie (@Laurad1989) reported

    @O2 I had to visit my mum to help her. I’m not with her now. I have access to her account and according to track my order in the app, the order is complete.
