    @O2 I am amazed by the lack of support from your network. Trying for a week now to get help and your help and advice is pathetic when you eventually answer.

  • gareth_thmpsn Gareth Thompson (@gareth_thmpsn) reported from Belfast, Northern Ireland

    @O2 you guys got a number to your payments team? I need to speak to someone. Automated IVR is poor.

    @seanp280 @O2 Where are you in Belfast? I live beside city hospital and I get full bars all over the city, 5G too! Only when I venture into the depths of County Down does it deteriorate lol

  • kkanecelt kierankane (@kkanecelt) reported from Belfast, Northern Ireland

Latest outage, problems and issue reports in social media:

  • Elliott_Dobbs Elliott Dobbs (@Elliott_Dobbs) reported

    EBITDA of nearly a billion in Q4 of 2021 alone, but you feel the need to raise your customers' prices by 8%... @O2. Will you be passing this 8% on to your employees to help them deal with the cost of living crisis? If not, why not?

  • journeytom T O M ✈ (@journeytom) reported

    @weste4 @O2 Part of the problem is enough people don't take action with their feet so to speak and just stay as customer

  • Louise63544316 Louise (@Louise63544316) reported

    @O2 The phone has been returned and I have been refunded for the payment I made upfront, the problem is your system billing me for things I no longer have and have already cancelled. I've spoken to someone who said it's a system error but this does not help when it's my credit file

  • bandersjatc ً (@bandersjatc) reported

    @O2 Hi, I’ve had no service since yesterday

  • K_GKennedy Katy Kennedy (@K_GKennedy) reported

    @O2 Hi I have tried on both WiFi and 4G and on my phone and desktop? I just need the code so that I can actually login to my priority account but it’s just not sending me the code

  • crasisz2 Crasisz2 (@crasisz2) reported

    @WTofficial @evanescence I'd like an explanation for this, covid restrictions have been lifted. Is this because of damage to @O2? What about giving people the option to change their ticket to a different location?

  • Acobbett Anna Cobbett (@Acobbett) reported

    @O2 tried to upgrade. No verification text received. Tried again. And again. Now been blocked and apparently have to go into one of your stores. Your WhatsApp “help” was worse than useless.

  • shaun_carter90 Shaun carter (@shaun_carter90) reported

    @O2 are you guys able to cancel an order I made today or do I need to call up? Was on hold for an hour earlier that’s all. Thanks

  • Allensmith81 Allen Smith (@Allensmith81) reported

    @virginmedia Sorry VM social media team I know that’s the scripted answer but while it’s a part of it an 11% rise when everyone is having a hard time already, except o2/vm who are literally making thousands of pounds a minute, stinks of customer abuse @O2

  • IITR07II 💪🐸👍 (@IITR07II) reported

    @O2 Recently even though it appears I have full signal, I can't use the Internet etc. (Mainly seen this when connected to 5G)
