    How come I get messages from @O2 telling me there is work in my area to improve service, and now I get a text from them telling me using WiFi for calls may be better quality... So pay for a service but don't use it is the message I guess?

  • liamtmaloney Dr Liam Maloney (@liamtmaloney) reported

    On tech help chat with @O2. It’s like some philosophical puzzle. “What’s the answer to your security question?” “I don’t know. What’s the question?” “Ah we can’t tell you that.” … “WHAT?!” It’s like Schrodinger doing customer service! Insane.

  • GarryLynch15 Garry Lynch (Owner of LTOA Taxis) (@GarryLynch15) reported

    @O2 can tell the world about all the good things they have achieved but the ultimate testament is how they treat their customers. Falsification and fraud on my account to win a case with the Ombudsman just sums them up! They do have form for Bribery and Corruption so who knows!

    @O2 what a joke, Virgin Media and O2 are sell this 360 package, Netflix and Disney together, should be a serving but O2, after four call to cancel this just took 25 pounds out off our account, please send the money back

    @O2 does anyone ever actually win. Been doing every priority competition for 2 years and never win a single thing

  • GlynAltair Glyn Jones (@GlynAltair) reported

    @O2 what’s going on with your data service in Glasgow? It’s a shambles right now.

  • nbrown_nicky Nicky Brown (@nbrown_nicky) reported

    @O2 So your response was be patient; it’s been six weeks of patience! 1st complaint made Aug 6th, 2nd 19th via email! how patient should a person have to be when they have sporadic service, having their life made miserable & having to make nr daily calls to you that lead to nothing?

  • walton_bhoy John Bhoy Walton (@walton_bhoy) reported

    @O2 You will take full payment next month when u clearly say my service will be effected by your work which is over a week. Paying for a service u openly state u can't deliver. I don't need network help tips just one thats working.

  • rhianna_joseph Rhianna Joseph #PrayForDemi ❤️ (@rhianna_joseph) reported

    @Jarners @O2 @Jarners to cancel the airtime plan customers have to give 30 days notice to leave or request a PAC to leave or request to be moved to Pay and go with O2.
