    @O2 @pchavda Having to reply from a colleagues phone. Reported this morning at 9 o clock. Still service-less. Bet you’re still charging full rental though.

    @O2 hi guys. My phone stopped working in Europe (since I added an Aussie E-sim). No one in your O2 UK shops can help. I even deleted the E-sim. But still: no roaming. O2 said I should wait until I’m in Europe for work again and call you (I can’t; that’s the point!). Help me, pls?

  • skbarrone Sarah Barron (@skbarrone) reported from Fingal County, Leinster

    @O2 Thanks. Problem started in London but same in Dublin. Everything works fine on Wi-Fi.

    @O2 @VirginMediaO2 Why can't I log on anymore since you "Joined up" absolutely useless Same "Log on issues" ...Set this up ...Set that up, Confirm it's you.... Nothing works. Im Not happy with O2 or Virgin locked out of my accounts, think I will close all 3 and go elsewhere.

  • ScottHolmes8682 Scott Holmes (@ScottHolmes8682) reported

    @O2 I have emailed the credit risk team to see what is going on with my application but I have not heard anything from them would you be able to help

  • Alec_McCaig Eck (@Alec_McCaig) reported

    @O2 Totally disgraceful customer service from 02. Been on the phone for over 3 hours to numerous advisors within customer complaints and no further forward. Every advisor stated they were the highest person we could reach, but eventually passed us to someone supposedly higher.

  • DeanBristow16 Dean Simmons (@DeanBristow16) reported

    @O2 Why is the O2 app still unusable. O2 you are a joke. The app has had 1 star reviews and complaints for years and it's still utter garbage

  • womaninblue1050 Marilyn (@womaninblue1050) reported

    @O2 @Coxy847 @virginmedia Stupid that Virgin signed up with you in the first place otherwise we wouldn’t be going through this purgatory now.

  • pomeroy1988 Luke (@pomeroy1988) reported

    @O2 Hello, my o2 phone is all of a sudden showing ‘NO SIM’ but has been working fine. Can you help me asap

  • paparuns Phil (@paparuns) reported

    Hey @O2 is there anyone that is actually able to help me with an open issue since July 25th? Your offshore'd CS teams have no access. I'm literally just trying to give you guys more money

  • s_mawds Stephen Mawdsley (@s_mawds) reported

    @O2 sick to death of a network I can’t get signal on. You are failing to fulfill your side of the contract by not probiding a suitable service. I’d like my contract made null and void or I will take my complaint to @Ofcom

  • Sarasota_Gooner Lord John Atkin (@Sarasota_Gooner) reported

    @O2 I have to make a complaint, please advise or message me the link to speak to a live agent
