  • sarahbennetto Sarah Bennetto: a comedian of sorts. (@sarahbennetto) reported from Fingal County, Leinster

    @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?

  • Amarpatel128 Amar Patel (@Amarpatel128) reported from Dublin City, Leinster

    @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.

  • Miss_GScience Tegan (@Miss_GScience) reported

    @O2 A brand-new phone was offered, but only at £14 more per month. I eventually accepted the device just to end the stress, not because the issue was handled well.

  • lunabhuna_ luna 🌙 (@lunabhuna_) reported

    @O2 I'm having trouble cancelling my sim only contract. I am within my 14 days cooling off period

  • Andree1990 Andree Wood (@Andree1990) reported

    @O2 please can someone message me regarding an urgent issue? Thankyou

  • egyptian_irish Kareem (@egyptian_irish) reported from Kilroot, Northern Ireland

    @O2 Migrating from O2 PM to O2 PAYG has taken 7 days so far, 3 phone calls of over an hour each and teams of people who have no idea what they are doing. Your customer service standards are shockingly poor and your back office processes are terrible. I can't wait to leave you

  • DarrenCoates Darren Coates (@DarrenCoates) reported

    @O2 when are customer services open?

  • MikeC0616129283 Mike C (@MikeC0616129283) reported

    @O2 O2 Plus Tariff, unable to connect in Japan (is listed as O2 Plus Data Travel Zone). SoftBank asking for Money when using O2 SIM. 4g&5g Signal Goes up and down randomly when sat still. Data Connection Log V.ODD. UK Banking Connection Firewall Alarm on Japan Mob Network. HELP!

  • lunabhuna_ luna 🌙 (@lunabhuna_) reported

    @O2 @O2 I have updated my settings. You may DM me. I will share my account details to cancel the account

  • Casserly_Rock James Casserly (@Casserly_Rock) reported

    @Vivsnewtwits @O2 Totally unprofessional, rude and basically showing contempt for you. Unacceptable.

  • xFaLLiNGxSnoWx2 xFaLLiNGxSnoWx (@xFaLLiNGxSnoWx2) reported

    @O2 Find someone to talk to me on here. My patience for this **** is wearing extremely thin.

  • Vivsnewtwits Vivi Rivi (@Vivsnewtwits) reported

    @O2 your "customer services" start calls with "hi dear" Do you think that's appropriate? It would be inappropriate if they were competent. As they are not, struggle to speak intelligible English and cannot resolve issues, it's particularly offensive.
