    @O2 Poor customer experience in-store today. Disappointed to say the least.

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

    @virginmedia @O2 But not your customer service when it comes to cancelling an order

  • KieranKelly1988 Kieran Kelly (@KieranKelly1988) reported from Derry, Northern Ireland

    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.

  • SianElin_PT Sian Elin Pedrick (@SianElin_PT) reported from Llanelli, Wales

    @MoneySavingExp I’ve been trying to disconnect from @O2 since I moved last November! Paying £18 a month despite not receiving any service from them!! They just told me that they can’t do anything as I’m tied into a contract!! Isn’t this a breach of contract @MartinSLewis

  • Jlsaunders3 Jade (@Jlsaunders3) reported

    @O2 worst signal EVER, wtf am I paying for. Wifi is down on and off all day (thanks @virginmedia ) and you’d think you can still use your phone anyway but NOPE 🙃 just pay @O2 **** loads for nothing 😒

  • WackyWendyWoo Wendy (@WackyWendyWoo) reported

    @O2 I need to speak to someone on online chat asap. My contract phone is from you directly and has some issues and is only 7 months old. Please can you help??

  • AdzCrawford2003 Adam Crawford (@AdzCrawford2003) reported

    @O2 If I take out an additional line on my account as an existing customer, do you run a soft search or hard search?

  • just_sansh Sansha Goddard (@just_sansh) reported

    @O2 this network is the worst ever I will never use them again once my contract runs out. Guys please don’t use them. #ripoff #ScamAlert

  • DjBilks Dj Bilks Official. (@DjBilks) reported

    @O2 yet again failed. Network coverage has been poor for a year. I was promised credit on my bill last year, that didn't happen. Recently I was advised it's a sim card problem. Sim arrived and same issue. Also no credit applied which AGAIN i was promised couple days ago. #o2

  • bryan_James1972 bryan James (@bryan_James1972) reported

    @O2 why can I no longer view my cctv cameras on your network? Why have you disabled port 8000?

  • DeepSteak Dr Magnus Pym (@DeepSteak) reported

    @LittleSausage @O2 @giffgaff All the major mobile phone companies are the same…they don’t give a **** about rural customers

  • dannigaynor1 Danni Gaynor (@dannigaynor1) reported

    @O2 absolute shambles. O2 algorithms has falsely thought my order was fraud and despite me telling customer service immediately it wasn’t - my phone due to arrive today has been sent back to O2. On top of that, 202 and fraud team can’t do anything about it to fix it. Laughable.

    @muddyme37 @EE @O2 Fancy a change? At Tesco Mobile we’re here to help. Not only do we guarantee we’ll never increase your bill mid-contract, we can save you money off your monthly food shop with Clubcard Plus 👍 - Laura
