    @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?

    @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€

    Hello @O2 you have put my 89 year old Dad on a £39/ month business tariff. That can’t be right, can it? We can’t access his account as it is a business type account so the app does not work. Please can someone from your customer services team DM me?

  • DRE93___ Daniel R Evans (@DRE93___) reported

    @O2 Hi, my partner upgraded her sim only contract yesterday and she is still with out signal. Can you please check if it’s been activated or why she still has no signal?

    @Doug_Paulley @LloydsBank @O2 I'm not a PCI expert, but from the PCI training I've had with work in call centres and using WhatsApp for customer service, I'd say it isn't. Whilst WhatsApp has end to end encryption, it doesn't stop anyone from inside the business accessing the chat and that message maliciously

    @O2 Unable to get to my free @GreggsOfficial coffee in app, says ‘voucher has been used’. Last time I used it was Tuesday. Can you help?

  • SusanAmbler5 Su Ambler (@SusanAmbler5) reported

    @O2 i did click and collect upgrade. unable to collect the phone as I couldn’t provide photo iD. If I’d gone into the shop and done it he would only want a bank card and current phone. Not impressed at all. A long term customer currently but maybe not for long.

    @O2 Been a customer for 12 yr. Upgraded last month and was misinformed on t&c. Contacted customer service within 14days. Was told someone would call me back. Today I received a call from my account manager, telling me I could have got it cheaper but now I can’t as I upgraded.
