  • 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.

  • dartduignan180 sean duignan (@dartduignan180) reported from Culmore, Northern Ireland

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

  • oharama Marian O'Hara (@oharama) reported from Derry, Northern Ireland

    @fionagordon5 @O2 One of the issues I have, retweet your compliant add BBCWatchdog and Which magazine to the post. This is ridiculous, need to get something done. The network was excellent now awful.

  • Alyshaa_134 Alysha (@Alyshaa_134) reported

    @Extinguisherman @O2 Should be in the terms and conditions somewhere about being able to leave the network if they aren’t holding up their end of the deal

  • Helena_Ann93 Helena-Ann🐝🐝 (@Helena_Ann93) reported

    @O2 is there anything I can do to boost my 4g/5g. I’m constantly having problems with my 4g/5g working.

  • wilcochris Chris Wilcox 🌻🇺🇦 (@wilcochris) reported

    @O2 It shows I have O2 Travel but doesn’t say that my tariff is a plus tariff and the help doesn’t say anything about the refresh unlimited being able to use O2 travel inclusive

  • sanecinema John Jencks (@sanecinema) reported

    Hi @O2 i have no phone signal anywhere for the past 4 days whilst in the USA on my UK iPhone. Please can you tell me how I can sort out. I’m trying to arrange a memorial for my father and it’s nay on impossible!

  • esspeearr Hotel Bastardos, San Domingo 🇺🇦 (@esspeearr) reported

    The signal for @giffgaff in Brighton is utter dogshit. Get @O2 to sort it out will you?

  • Extinguisherman Dale Watts (@Extinguisherman) reported

    @Alyshaa_134 @O2 If you go ombudsman route, start a log of all the times network Isn’t working, get some proper evidence, location time, what’s not working and postcode. I failed to do that and cost me.

  • allymcgeorge Alvin TX Fernandez (@allymcgeorge) reported

    @O2 hi, if I chose Disney+ as an extra, and I already have it- do you just cancel my existing contract and set up a new one?

  • Dr_Kareem_UK د. عبدالكريم القويضي (@Dr_Kareem_UK) reported

    I really don't know what happened to the network coverage of @o2! I'm visiting the UK for the past 2 weeks as a tourist, and have got the PAYG sim with what's supposed to be 100 GB data for £30. It's been a very bad experience - no or a very bad network at almost all places!
