    @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.

    @BradyHaran @O2 One time I disabled Airplane mode while flying over Canada, I somehow managed to get some cell service and realized that when I received a text message saying my bill was reaching 80€

    @O2 hi. My friend’s UK mob stolen in Dublin. Need to cancel/freeze fone account. Help!!

  • 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?

    So you split with an abusive partner and when trying to sort the finances, speak to @O2 to see how they can help you not pay for him anymore. Their solution? Contact said abuser and sort it with him otherwise you're stuck in contract and have to pay

  • DaiWrighty David Wright (@DaiWrighty) reported

    @O2 if I pay off my device plan early, can I cancel my airtime contract without any termination fee? Airtime plan ends March 2023.

  • callumjohn28 Callum (@callumjohn28) reported

    @O2 I signed up to travel yesterday and it’s still not working… Just received a text saying i’ve used my 50MB of data. Help?!

  • JadeWatton Jade Watton (Taylor's Version) ❤️🧣🎀 (@JadeWatton) reported

    Hi @O2 I have been waiting for 2 weeks for a reply email from O2 complaints, with the issue going on for months.

  • little_lea16 Lea 🇬🇧 🌹💞 (@little_lea16) reported

    @O2 I want to cancel my 30 day plan sim with yourselves. I don't want to wait hours on hold on the phone. I'm fed up of the monthly charges secretly increasing, without any notice, despite being on unlimited! I can get a cheaper deal elsewhere!

  • Emmaaa__x Emmaaaaa (@Emmaaa__x) reported

    @O2 customer service is actually shocking like I’m absolutely fuming. Absolutely waste of time 30 minutes on the phone to be speaking to someone who doesn’t know what they’re doing!!! I want this resolved now!

  • Ag3ntVibeZz Antony Thompson (@Ag3ntVibeZz) reported

    @O2 I’m on a o2 refresh contract. I got my phone yesterday. Put in my new sim. Text swap to the number I was given and it worked last night and today until around 12 today. How can I fix this??

  • bendougcraig Ben Craig (@bendougcraig) reported

    @ThreeUKSupport It’s pretty much everywhere. And yet people on other networks don’t seem to have the issues. And if I upgrade I’ll have to pay roaming fees. Unlike say @O2 So at the moment I see very little point in staying with you. You take my money and I get very little in return

  • tracestarshine Tracy Allan (@tracestarshine) reported

    Appalling customer service from both @dhlparceluk and @O2. Phone addressed to and delivered to wrong address. Signed for by DHL driver himself. Deliver to an unoccupied house!!! Nobody calling me back to resolve the situation. What do I do now??? @O2 what do I do now??

  • barclaybatch David Batchelor (@barclaybatch) reported

    @O2 Any update please? Now in my fourth day with no service at all.
