    @O2 Poor customer experience in-store today. Disappointed to say the least.

    @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.

    @O2 ur network is terrible! Wish i never moved. Talk about miss selling. I am lucky to ever have sustained 4G let alone 5G

  • mohulbert Maureen Hulbert (@mohulbert) reported

    @o2 get your act together I've had no signal for 18 hours now KA11 3BU area 30 minutes hold fir customer service

  • ashgoldy Ash (@ashgoldy) reported

    Hey @O2, turns out adblockers block your website content so I can't log in with a security code as it never appears. Should probably fix it.

  • eileennewell15 eileen newell (@eileennewell15) reported

    @VMO2News @virginmedia @O2 After Virgin did planned work in my area my landline did not come back on. 7days now. Tech has been out numerous phone calls several on line complaints ignored, No landline. Noone bothers to get in touch. Appalling service. AVOID!

  • SianElin_PT Sian Elin (@SianElin_PT) reported

    @itsthesd @O2 As if anyone is going to make sure they have a phone signal before making sure they have a roof over their head!! 🙄

  • char_charmed 💥🧙‍♀️🔮ForeverCharmed🔮🧙‍♀️💥 (@char_charmed) reported

    I can't believe how awful @O2 is, i have 2 numbers with them. One of my numbers have been cut off and other number i haven't been able to use for 3 weeks. I have cancelled my direct debit and i wont be reinstating it until both line are up and working!...

  • tisha_wisha86 tisha (@tisha_wisha86) reported

    No been able to use my phone for 3 weeks unless connected to wifi. Cant be reachable for my kids and cant do my job properly. All because @O2 are changing their towers to 5g. That sounds like an o2 problem as I am paying for a phone I can not use. Is anyone else effected by this?

  • RawBeard Märk Räwlings 🤘 (@RawBeard) reported

    After waiting 7 days for a replacement SIM from @O2 (fair enough it was delayed due to a bank holiday and a strike) it finally turned up today. Put it in my replacement iPhone… and nothing! After trying everything I can think off I finally contact O2 support. 1/3

  • Jimbobthon James Richards (@Jimbobthon) reported

    @O2 Another day, and yet another issue of my signal dropping off. Sitting in a coffee shop, can't use my phone without WiFi as apparently it's "emergency calls only" through o2 but EE was 4g+. And yes, I was by the window

  • SJamesAuthor Steph (@SJamesAuthor) reported

    It’s funny how @O2 @tescomobile and @virginmedia all say there is nothing wrong with the signal in my house, yet it drops constantly. Even tweets take a long time to be sent. I wish they’d just be honest and admit it’s crap in my area, than keep lying to my face.
