    @virginmedia @O2 But not your customer service when it comes to cancelling an order

  • KieranKelly1988 Kieran Kelly (@KieranKelly1988) reported from Derry, Northern Ireland

    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.

  • JamiePayner22 Jamie (@JamiePayner22) reported

    @dodo_1980 @hughesclaire39 @O2 Yep totally agree , signal is awful, says I have 4g or 4g+ yet nothing loads , and they're getting really expensive, but like you said they don't charge aboard , when my contract is up I'm going elsewhere and will just pay the roaming charges , works out alot cheaper

  • SleekSlicker Dominik Szweda (@SleekSlicker) reported

    @O2 yet another futile attempt at communication with O2. Definitely amongst the worst customer service experiences in my life. I just want to leave at this stage and can’t.

  • siankeira sian bennett (@siankeira) reported

    @O2 They must not be with O2 if they have been able to text on there phone! The worst signal provider, and shoddy customer service.

  • JamiePayner22 Jamie (@JamiePayner22) reported

    @hughesclaire39 @O2 Same as me , there're really expensive now and signal is awful , when says I have 4g or 4g+ and yet nothing loads up , but like you said they don't charge abroad but when my contract is up I'm moving network and just going to pat the roaming charge, still save loads

  • mobsy69 Omar Nadhmi (@mobsy69) reported

    @hughesclaire39 @O2 Couldn't agree more, the coverage is really bad, I'm thinking of switching network

  • BrianMa63080971 Brian Martin (@BrianMa63080971) reported

    @O2 Hey, O2 - why is nobody answering your phones for a second day in succession? Why have you unlawfully stopped my service when you owe me money? Do you call this service? NAMED AND SHAMED!

  • KyleEvans210505 Kyle (@KyleEvans210505) reported

    @O2 I don’t disappoint i got the 14 pro max too bad I’m not at school

  • RennicksShev Shev rennicks (@RennicksShev) reported

    @O2 There’s no point-it says the mast is not working constantly!

  • BrianMa63080971 Brian Martin (@BrianMa63080971) reported

    @O2 STILL on hold - unbelievably bad service. Agent speaking over me and shouting at me, refuses to assist me and refuses to transfer me to a manager. Agent refusing to transfer me, alleging "no managers available". Agent is now silent, call time now ridiculous.
