    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 Poor customer experience in-store today. Disappointed to say the least.

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

    @rhianna_joseph @O2 @Settldsupport Thank you Rhianna. It's all done now thankfully, O2 were the last company I had to notify and the worst. I hadn't heard of Settldsupport as I would have used them. xx

  • magrim123 Mark 'Charlie' Magri-Overend (@magrim123) reported

    @O2 Thanks for your response, but that phone number only works if you know the associated mobile number, which I dont know, cos I never used the service. Please give me a phone number to actually speak with someone.

    @O2 This is getting unbelievable I am so angry right now you are putting 5G in the middle of nowhere instead of what you said that you were putting it in city’s first I live in Exeter and I never get 5G the only place I get 5G is going into some random farmers field

  • rosstheconsumer Ross (@rosstheconsumer) reported

    Hi @O2, how can I cancel an order I placed - which said was in stock at time of ordering - but was actually out of stock 10 mins later. I can’t see the order on myO2 so how can I cancel it?

  • magrim123 Mark 'Charlie' Magri-Overend (@magrim123) reported

    @O2 ...and the O2 Contact No in the O2 email (08448090202) doesnt work for me

  • c_l84 Better Call Col (@c_l84) reported

    The last few weeks the 4G network for @o2 wherever I go has been nothing short of shocking! Phone might as well be a paperweight.

  • sarahdow05 Sarah Dow (@sarahdow05) reported

    @O2 yet again ‘ No Service’ on my phone.

  • Gav_Ivison 🄶🄰🅅🄸🄽 (@Gav_Ivison) reported

    @O2 lads what's going on with the signal lately?

  • moustachedmedic kenny janes (@moustachedmedic) reported

    Am happy to say I am now the non owner of the #GalaxyWatch4 after returning it. @O2 have said that in order to recieve calls, the Bluetooth settings must be turned off? Not helpful when using buds to play music. The battery lasts 5 hrs also. Poor watch, avoid if possible.
