  • 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.

  • JeremyAdamsNI Jeremy Adams (@JeremyAdamsNI) reported from Belfast, Northern Ireland

    @O2 AirPods and 🎅 is looking after them! Again fantastic service.

  • IanRobinson Ian Robinson (@IanRobinson) reported from Stormont, Northern Ireland

    @chriswb @O2 No. Plus it says No Service where the O2 logo should be. I might try the SIM in my O2 iPhone.

  • gareth_thmpsn Gareth Thompson (@gareth_thmpsn) reported from Belfast, Northern Ireland

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

  • padraigmc1988 padraig mc crory (@padraigmc1988) reported from Belfast, Northern Ireland

    Is it just me or has @O2 phone signal went to the absolute dogs?

  • 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).

  • catherine271076 Catherine Dwyer (@catherine271076) reported from Jordanstown, Northern Ireland

    @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.

  • liznangel3 Liz Cullinane (@liznangel3) reported from Balmoral, Northern Ireland

    @EmmandJDeSouza Burnfoot, Donegal house in Derry UK Workshop Donegal, Irl @O2 flicking from roaming to home constantly, useless turning it off roaming I'd never get any work done👿

    @seanp280 @O2 Where are you in Belfast? I live beside city hospital and I get full bars all over the city, 5G too! Only when I venture into the depths of County Down does it deteriorate lol

  • bethym09 Beth Mitchell (@bethym09) reported

    Please avoid @O2. Can't manage their direct debits, blame customers for their internal errors, complaint process is non existent I'm left with a damaged credit rating and constant payment issues. They're service is abysmal. I've been hung up on, laughed at, LIED TO etc!

  • SB_londonxo SB (@SB_londonxo) reported

    @O2 hello my data was down yesterday and I’m not entirely sure why as my bill had been paid for the month. I went the whole day without internet.

  • vikkigregory Mrs Simmo (@vikkigregory) reported

    Absolutely disgusting how my husband has been treated by @O2 he has rang everyday for 2 weeks even been in to the local store to get help with his account,no one is helping or can help or ringing back! He’s paid his bill twice over the month and been cut off #awfulcustomerservice

  • chloeannelillia chloé (@chloeannelillia) reported

    @O2 is there anyone i can contact about my bill? i paid my phone off over a year ago and the contract was supposed to come down yet i’ve noticed i’m somehow being charged more than my old contract?

  • sportymale33 Mark Davison (@sportymale33) reported

    @O2 I’m not happy at the treatment I have had I have closed a business account the call handler told me an amount I then paid it that doesn’t mean you can then charge me a fuse then £200 on top of what I have paid 3 months down the line it’s just not acceptable

  • GardensByPoole Paul Western Esq (@GardensByPoole) reported

    @O2 I’ve deleted it, but it would help if @o2 & co. spent more time looking for a solution.

  • kaaatzx KT (@kaaatzx) reported

    @O2 home thinking it was an area issue - no signal at all, what’s going on?

  • RatcliffeKeely Keely Ratcliffe (@RatcliffeKeely) reported

    @O2 called you 4 times in the last hour and everytime u have answered the phone u have put the phone down. Worst thing is I spoke to someone this morning who said they had dealt with my issue and you still haven't. Amazing how I only renewed my contract Friday.

  • sportymale33 Mark Davison (@sportymale33) reported

    @O2 I think your call handlers absolutely suck at there jobs they simply don’t do the job properly I’m fuming at the way I have been treated and I’ve been a customer for 20 years I’m seething at the treatment if all your customers the same you will simply go out of business

  • marycrook1 mary crook (@marycrook1) reported

    @O2 O2 customer service is terrible. Mobile contract upgrade billing issue.12 calls to 202 (205mins) and told atleast 5 times that my grievance would be escalated to senior admin. Nothing,no update,no resolution! EXCEPT Debt Collection letter!?? Come on @O2 , Sort it!!
