  • TheRealJackieJ Jackie Johnston (@TheRealJackieJ) reported from Castlereagh, Northern Ireland

  • GeorgeCowan Britishgamerni 🇬🇧🏳️‍🌈 (@GeorgeCowan) reported from Newtownards, Northern Ireland

  • DoIKnowMyself Charlotte (@DoIKnowMyself) reported

    @O2 I sent you a DM last night about the problems I'm having with my new phone/sim Please can you get back to me asap. This is urgent. Thank you

  • tattoomrmagoo Lewis McNamara (@tattoomrmagoo) reported

    @O2 my job entails me needing it all hours especially now as a keyworker. I couldn't send it to be repaired and the issue would have happened again. My issue is the T&C absolves you entirely & penalises me financially, when you'd never have offered anything other than repair..

  • manx_maid Stephanie Brooke (@manx_maid) reported

    Well gee thanks for that *13* hour outage, @O2 . . (no I haven't been asleep - breathing not up to that today #LongCovid)

  • waynester21 Wayne Kinder (@waynester21) reported

    @O2 What do I have to do to contact you? Every single time I use the app to talk to someone it says you're all busy. That's 3 days straight now. I want to cancel my SIM only deal. I've not even used the SIM. How can I cancel it? Thanks.

  • Rodeyeart Rodrigo (@Rodeyeart) reported

    @O2 I am currently in Colombia and stuck, so I am unable to dial 202 for support, you have cut my service Can you advise and reactivate my service as soon as possible ? My number is +44 7545 133269 account holder Boris Rodriguez

  • tattoomrmagoo Lewis McNamara (@tattoomrmagoo) reported

    @O2 I've already asked for the phone to be returned, the mainboard, digitizer, fingerprint sensor and camera / mic array are worth more than £27. There's a gaping hole here with the process and your customer service just quoting "out of house insurance t&c" is pitiful.

  • HollyR88 Holly Robinson (@HollyR88) reported

    @O2 Unfortunately no, I don't just have a random phone. Its done the same again today, no notification of a voicemail until a few hours later. Maybe its a provider issue? As I've never had this issue before! Also had the phone for 2 years and no issues

  • bebangtheory B (@bebangtheory) reported

    @O2 what's the matter with your signal?? Every week I there will always be episodes of me not being able to make and receive phone calls. I am having the same problems today again for the past two days!

  • Gti_princess Sarah McCoy (@Gti_princess) reported

    @samsteele771 @EE That’s why after 13years with them we left them! I’m glad we did @O2 are far better and when I was called my EE the man was incredibly rude to me! 😡

  • Sam_Leighton83 Samantha Leighton (@Sam_Leighton83) reported

    @O2 trying desperately on your website to find where I chat to a customer service person about reinstating two PAYG sims and it keeps sending me in circles!!
