    @O2 you guys got a number to your payments team? I need to speak to someone. Automated IVR is poor.

  • BrendanB2 Brendan Bonner (@BrendanB2) reported from Belfast, Northern Ireland

    @O2 I wouldn’t recommend anyone buying online and redeeming your phone. Go to the store, you can’t trust any of the online and virtual services. Was a handling getting phone set up, getting help and they only give you 50% of the value they say (no matter how good your phone is).

    @O2 I need to escalate a complaint re. a member of staff who refuses to to 1) process my upgrade and 2) who has just terminated my call. Who can I talk to? Your staff say it’s not possible to talk to a manager.

  • thebaldfather Hugh Pollock (@thebaldfather) reported from Belfast, Northern Ireland

    @O2 I am amazed by the lack of support from your network. Trying for a week now to get help and your help and advice is pathetic when you eventually answer.

  • apallan ANN P V ALLAN (@apallan) reported from Belfast, Northern Ireland

  • Andy_TheGrouch Andy (@Andy_TheGrouch) reported

    So bored of @O2 being unable to maintain 4G or a phone call wherever I go. ‘No network problems in your area’ well there clearly is. Garbage.

  • Wlee980 lee_1🏳️‍🌈🏳️‍🌈 (@Wlee980) reported

    @tteahydrated @O2 Talk to @M_leemah they helped me when support services wouldn’t help me🥺..

  • JB51887913 Jim (@JB51887913) reported

    @ChloeLeaAnnSte1 @O2 Hi, did @o2 confirm it’s down? I’ve had same problem all day but they keep giving scripted response “use signal checker online” there’s definitely a fault but why aren’t they informing customers? Pay an absolute fortune for this poor service!

  • JB51887913 Jim (@JB51887913) reported

    @o2 what’s happening with service today? Had no signal for calls or text and no 4g all afternoon? Your standard response is to use network status checker. It says no fault but clearly there is. I’m south and family up north with same issue today

  • tteahydrated Katie (@tteahydrated) reported

    @O2 hi, my bank account is linked to a contract which I don’t have control over. It is my ex’s phone but they are failing to pay me for the contract. I need to either close the account or unlink my bank details. Please can you help?

  • BrentfordHarry Harry (@BrentfordHarry) reported

    @O2 your service is a ******* joke.

  • On_Air_Lewis Shaun Lewis (@On_Air_Lewis) reported

    @AppleSupport not able to make or receive calls on my iPhone 13 whilst roaming in Spain on Movistar via my home network @O2. 5G drops to 3G when making calls and it just fails. GibTel is ok as it calls using 4G. iPhone 12 is ok. No bars and roaming activated. Very frustrating.
