  • KieranKelly1988 Kieran Kelly (@KieranKelly1988) reported from Derry, Northern Ireland

    Quite shoddy of @O2 to refuse me a contract as a new resident of Northern Ireland when my driving licence is in the Republic of Ireland and not offer an alternative verification or reply to my email of complaint from 6 days ago.

  • oharama Marian O'Hara (@oharama) reported from Derry, Northern Ireland

    @O2 Poor customer experience in-store today. Disappointed to say the least.

  • dartduignan180 sean duignan (@dartduignan180) reported from Culmore, Northern Ireland

    @virginmedia @O2 But not your customer service when it comes to cancelling an order

    @socoedjones @O2 Over this past week I've struggled to get decent signal at work. Nothing at work had changed, yet the signal is crap 😔

  • MitsP2012 Mits (@MitsP2012) reported

    @O2 can you help with a payg number that has been disconnected? #customerservice

  • Matthew_Wood85 Matthew (@Matthew_Wood85) reported

    What's going on @O2 ? Lately my mobile signal at work has been terrible! I've been with you for so long but I'm actually considering moving providers. #mobilesignal #O2

  • Kealan_ K! (@Kealan_) reported

    @O2 Im on the phone now but I don’t think there’s anything you can do to help? All I want to do is buy some new airpods 😭

  • rachael__coutts Rachael (@rachael__coutts) reported

    @O2 just a warning to everyone to never go with o2 for any kind of business! They don’t deserve your money. Been a customer since I had my first phone and they couldn’t care less about you or any problems you might have. Just a shower of money grabbers really!

  • socoedjones Sophie (@socoedjones) reported

    @Matthew_Wood85 @O2 I moved to 3 from 02. Signal was great for 6 months or so. I can't get signal in the town centre now. Would love to know what's going off.

  • lucyolix lucy (@lucyolix) reported from Salford, England

    @O2 is the signal down in Salford? Data isn’t working and the signal is either none or just one

  • rachael__coutts Rachael (@rachael__coutts) reported

    @ChloeMcfee @O2 And they replied to me saying “dm us like we’ve asked” honestly how ******* rude is that hahahaha fuming

  • bubblegram__ Julia (@bubblegram__) reported

    @O2 s costumer service is just appalling! No one cares to help. Will not be renewing my contract!

  • jimmyll04218854 jimmy lloyd (@jimmyll04218854) reported

    @O2 Yep same problem we’ve had from start. Seems crazy that you can sell a contract for a 4G (even 5G) phone, then issue one that doesn’t provide those services but still expect to have the (unfulfilled) contract honoured. For context had to buy a PAYG @EE handset to work on move
