  • felixeemopener simon bennett (@felixeemopener) reported

    @whos81 @O2 It’s the same with me for Vodafone. I think it’s a bandwidth issue. Too many people and not enough web

  • eastmandoo AE (@eastmandoo) reported

    @O2 after a 80 minute call over 3 weeks ago to customer services ( told me matter was resolved) to another call today to be sent to store for store to contact customer services for me to be told they can't do anything . Worst company in the world @O2 sucks . Disgraceful

  • weebtrashperson Hayley C (@weebtrashperson) reported

    @O2 You have no reported issues. I just have zero signal meaning I have missed important calls today. Annoyingly its somehow still legal for you to put in your contracts that you don't guarantee service so im stuck @Ofcom

  • ASHARNETT Ash Arnett (@ASHARNETT) reported

    @O2 Fantastic I bought them from you, online and am still paying for them. Have taken them to an iPhone approved service centre and they have said it’s a hardware fault and they said to speak to Apple who I spoke to and they have confirmed it sounds like a hardware issue.

  • Connor_James94 Connor (@Connor_James94) reported

    @O2 it’s truely insane how terrible my time with this company has been. I couldn’t honestly recommend them to anyone. From signal issues in a city centre, to finding it next to impossible to speak to a human when you need to. Go anywhere else

    @O2 the complimentary ocean tickets are always unavailable or out of stock when I try and claim them. I’m aware they’re released at 2pm on a Wednesday but always out of stock. Is there an issue with the app?

  • Glencox1986 Glen Cox (@Glencox1986) reported

    @O2 had no service for 2/3 days now around Tadworth, understand there’s an issue with one of the masts near here but I work from home and this is a real pain. Any significant update?

  • TexasBliffEm Matthew (@TexasBliffEm) reported

    @O2 I want to cancel my contract. Can someone contact me about it?
