    Hi @O2. If you received a notification that a sound was played from my phone, please don’t worry. I was just testing out the Find My app on my iPhone, as I’ve never used it before, so I just wanted to check it out and see how it worked. Thank you and sorry. :)

  • Daniel_Lyddon Daniel Lyddon (@Daniel_Lyddon) reported from Cardiff, Wales

    (1/3) Sad to say that @O2 are now trying to charge me for a service never used, when I cancelled a mis-sold contract within the 14-day cooling-off period. Almost two months later they're now saying they're going to charge me a late payment fee, plus the bill...

  • themarkhawkins Mark Hawkins (@themarkhawkins) reported from Barry, Wales

    @viv_wilson @O2 I am in CF62 area, I haven't been able to get more than one bar for years, forget 3/4g Only keep it as I get a good signal in work.

  • Daniel_Lyddon Daniel Lyddon (@Daniel_Lyddon) reported from Cardiff, Wales

    This weather properly has me over a barrel. Mistreatment by @O2 properly has me feeling down. My #CovidVaccine pain is bad. Some days the demons are just too much to battle...but today is not one of those days. Rest, relax, refocus. #MentalHealthMatters #BipolarDisorder

    @O2 That didn’t help me access the manage my 02 wifi & wont help me when I’m on the London Underground??

  • aeron_dudas aeron dudas (@aeron_dudas) reported

    @O2 That was in September 2022 and they said they would credit me for the affected area. But it's almost 2023 and they haven't fixed the issues.

  • aeron_dudas aeron dudas (@aeron_dudas) reported

    @O2 Nothing they just credited my account. But the issue is still there! That's the problem throw money as compensation rather than fix the issues with the network.

  • join4te Jay (@join4te) reported

    @O2 Day 46 of 365 on trying to get O2 to fix their phone customer service. 1) If you ring and ask for an e-sim for an Apple Watch then good luck with that. Staff seem very untrained. 2) Calls disconnect too much when speaking on 202. 3) The whole IVR system feels dated.

  • jolecoma Joseph (@jolecoma) reported

    @O2 my free odeon ticket voucher is not working. Keeps saying ‘the voucher number is incorrect’. Can you please help?

  • jezrab Jeremy Rabinovitch (@jezrab) reported

    @O2 A week on and still no further assistance from you. What does it take for you to actually help your customers?

    @jolecoma @O2 Hi, I'm having the same issue. By any chance were you trying to book Avatar?

  • shaun682 shaun68 (@shaun682) reported

    @O2 Worst network and customer services ever!!! Signal is really poor and they have got my bill wrong for the past 3 months. Speak to customer services and they just say it will get sorted. Suggest people choose another network because O2 are rubbish.

  • LifeofLL LL (@LifeofLL) reported

    @Xilisaaa @O2 Hi, just wondering if you managed to get this sorted. I'm having the same issue
