    @BradyHaran @O2 One time I disabled Airplane mode while flying over Canada, I somehow managed to get some cell service and realized that when I received a text message saying my bill was reaching 80€

  • sarahbennetto Sarah Bennetto: a comedian of sorts. (@sarahbennetto) reported from Fingal County, Leinster

    @O2 hi guys. My phone stopped working in Europe (since I added an Aussie E-sim). No one in your O2 UK shops can help. I even deleted the E-sim. But still: no roaming. O2 said I should wait until I’m in Europe for work again and call you (I can’t; that’s the point!). Help me, pls?

  • skbarrone Sarah Barron (@skbarrone) reported from Fingal County, Leinster

    @O2 Thanks. Problem started in London but same in Dublin. Everything works fine on Wi-Fi.

  • 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!

  • TheTyChapman Tyler Chapman (@TheTyChapman) reported

    @O2 why is your connection so bad in the Scarborough area! Ive been with you for possibly 10 years, but service is rubbish! Doesnt work in my house unless connected to WI-FI and at work its ultra slow! Temped to move services

  • 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

  • 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?

  • 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.

  • SimpsonHeather_ Heather Rilling (@SimpsonHeather_) reported

    @O2 absolutely horrendous customer service from you guys today and for the past week to be honest, upgraded with you and still waiting for the phone to arrive, been a whole week now and just had a really rude o2 customer service woman hang up on my husband - what now O2??

  • Alanphipps8 Alan phipps (@Alanphipps8) reported

  • xchloebb chlo (@xchloebb) reported

    @O2 @O2 Hi I have been tracking my order and contacting your team, since the 12/04 still nothing. Absolutely terrible!!

  • ElenaGretina Ella (@ElenaGretina) reported

    @O2 the poorest customer service. Always telling me lies. Regret joining: :(

  • 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.
