  • 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

    @O2 is there any reason why my signal is crap at the minute? Used to be best in the area so signed up for a 24 month plan and since then crap

  • YBG66 Julie KINGMAN (@YBG66) reported

    @O2 #Terrible Customer Service ... my phone won’t do ANYTHING & the guy left me on hold for 45 minutes, never to return 😡

  • RachelRainbow Rachel Rainbow (@RachelRainbow) reported

    @O2 why is it impossible to talk to a person on your customer service line 15 calls and only twice have i got to a person and both times been disconnected 😡😡

  • CraigLindley Craig Lindley Olney (@CraigLindley) reported

    @O2 Absolutely shocking service happening right now! On hold and passed between 4 advisors and not one of them prepared to take ownership of a simple request to transfer ownership from one member of the family to another. A shocking sales ploy to prevent you leaving @02 1hr35min

  • GraceOliviaa_ Grace Kousoulou (@GraceOliviaa_) reported

    @O2 been on hold for almost an hour and 45 mins trying to sort an issue with my contract that was caused by your advisor giving false information. Absolutely terrible customer service 😡😡😡

  • SamiDrawz Sami 🐢サミー (@SamiDrawz) reported

    @O2 I sent a DM can you help

  • helenkerr23 Helen (@helenkerr23) reported

    After over 20 years of loyalty I am officially saying goodbye to @VodafoneUK! New phone order direct from @Apple and new SIM card from @O2. Saving over £20 a month & maybe I will get to deal with a real person if I have an issue rather than the worlds most annoying bot TOBI!!

  • TimPBreden Tim Breden (@TimPBreden) reported from Arundel, England

    An hour on Live Chat at @O2 only to be told they haven’t done what they promised THU & FRI. What they will do is make sure the back end team, who they assured me yesterday, will do today what they promised 24 and 48 hours ago, why do I think I’ll be on Chat tomorrow? #O2 #awful

  • Jadeeeyy09 jade (@Jadeeeyy09) reported

    @O2 can’t get a hold of anyone to speak about my bill? Clicking on support just takes me in a loop, ridiculous.

  • MeatGrinder49 Jamie (@MeatGrinder49) reported

    @O2 Hi there, I recently joined O2 and I'm looking to keep my old number from SKY Mobile however I seem to be having some trouble doing so. Some help would be appreciated.
