    @O2 hey so you say you’re got the social tariff and new customers can get said tariff yet customer services and sales refuse to issue said tariff I’m pretty sure that’s against the rules @Ofcom ?

  • Josephmsum Joseph Summerfield (@Josephmsum) reported

    @O2 can I cancel my contract due to your **** service and "system limitations"?

  • womaninblue1050 Marilyn (@womaninblue1050) reported

    @O2 @Coxy847 @virginmedia Stupid that Virgin signed up with you in the first place otherwise we wouldn’t be going through this purgatory now.

  • 12cupsaday dickie (@12cupsaday) reported

    @RedRosesRugby @O2 Good win but sort the handling errors out

  • InfernalBore Richard (@InfernalBore) reported

    The collapse of @o2businessuk @O2 customer service has been crazy. After an alert for potential fraud on our account, we've been ignored, lied to and shrugged off for a more than a month by a series of customer service managers. So incredibly poor.

  • stridemat stridemat (@stridemat) reported

    @O2 Is it possible to add an Apple Watch data plan to a rolling 30 day contract on the O2 network in the uk?

  • VronP7 Veronica (@VronP7) reported

    @O2 I’ve just trued again and it says clearly if you want help go on to twitter. What do you expect me to do do now

  • Iam_njd Nicola (@Iam_njd) reported

    @O2 The issue is you have ascribed a number to my account that’s not my account so I can’t log into anything to get help 🥲

  • StevieFraser375 MediumStevieFraser (@StevieFraser375) reported

    Not impressed with @O2 customer services at all. On hold for well over 20 minutes, switched between 4 different depts and each contradicting each other with information regarding my enquiry. Gave up in the end as they just wouldn’t listen

  • Sarasota_Gooner Lord John Atkin (@Sarasota_Gooner) reported

    @O2 I have to make a complaint, please advise or message me the link to speak to a live agent
