    @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

  • 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.

    Can you tell me how I can I can cancel my contract with @O2 I’ve been going round in circles on there website

  • SarahNuzum Sarah Nuzum (@SarahNuzum) reported

    @O2 I’ve been without any real phone signal at home for over four days now. Apparently any upgrade work was meant to be completed tonight. This isn’t ideal when trying to work from home. When will full signal be restored?

  • robotpinemarten Dino is tired (they/ them 💙❄️ 🏳️‍🌈🏳️‍⚧️) (@robotpinemarten) reported

    Hi @O2 I got a free 6 month Disney+ subscription and I want to cancel it before I’m charged but I can’t work out how to do it

  • Yorkie_Jock Derek Libberton 🏴󠁧󠁢󠁳󠁣󠁴󠁿 (@Yorkie_Jock) reported

    @O2 how do I speak to customer services? Dialling 202 and keep going round in circles before being cut off

  • David_Quinn87 David Quinn (@David_Quinn87) reported

    @O2 So after just 13 days I’ve had to call support multiple times, endless DMs and now a day spent on online chat. Now I’ve been left stranded in Ireland with no signal after being hung up on earlier by tech support. #Appalling

  • Wcroft84 Wez Croft (@Wcroft84) reported

    I wish my data signal was as high as the cost of my phone bill. Thanks @O2 for a signal so weak I may as well be on Mars.

  • bluenose1891 bluenose81 (@bluenose1891) reported

    @O2 issue with ur 4G today???

  • Hotlips1000 Holly Giddings (@Hotlips1000) reported

    @O2 interesting that your customer service advisor sold me an essential ‘pack’ for my new Apple upgrade which includes an iPhone cover and new charging pad (for £45). Whilst Probably knowing you can’t charge your phone with a solid hard cover on. Feel very duped today.

  • unfortunatalie Nat Guest (@unfortunatalie) reported

    I'm trying to upgrade my phone with @O2 because mine has stopped bricked itself and to complete the order they have to send a text to my number to confirm it's mine and apparently no one considered this might be, you know, an issue?

  • LouisaUpcycler Louisa (@LouisaUpcycler) reported

    @O2 signal keeps cutting out, can only get enough signal to tweet this at highest point in house. Can't go outside to test as weather is nasty. I'm in Pontypridd. Is there an issue here? I work at home.
