    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.

    Is a cellular Apple Watch looked to the network provider you get it from? I have a Stainless Steel Series 6 that I got from @O2 that I no longer need since I got my Ultra from O2.

    All you have to do is fart and your @O2 signal dies!

  • CloudJKay Jon (@CloudJKay) reported

    @O2 But there is no resolution! DAY 9 of no number being ported and the old number being dead. Can I turn your phone off for 9 days and see if you are happy with a canned response from support?

  • Hazel_Stones Hazel Stones (@Hazel_Stones) reported

    @O2 @TheO2 @peterkay_co_uk The app is crashing after login (VM customer)

    @O2 Even though you can’t sign in through the app. Jokers

  • SeanRJordan Sean R. Jordan (@SeanRJordan) reported

    Don’t think I can recommend @O2 to anybody. Customer service has been shocking. I’m currently waiting on them calling me back with an update but haven’t got much hope.

  • CLizzle86 Carey Canavan (@CLizzle86) reported

    @O2 Still no response from anyone at 02. How long do I have to wait for a response for an issue that arose in August? I do not have time to continually chase this. If there is no response in 5 working days I will be contacting the ombudsman

  • ZeyjanLazaro Zeyjan Lazaro (@ZeyjanLazaro) reported

    Hi @o2, my voicemail seems to have stopped working, how can I fix it? Thank you!
