  • little_lea16 Lea 🇬🇧 🌹💞 (@little_lea16) reported

    @O2 I want to cancel my 30 day plan sim with yourselves. I don't want to wait hours on hold on the phone. I'm fed up of the monthly charges secretly increasing, without any notice, despite being on unlimited! I can get a cheaper deal elsewhere!

  • _AllTheSocials_ Slippery Biscuit (@_AllTheSocials_) reported

    @roviediamond @O2 @O2 customer service sucks big time. I bet it would be different if they didn’t have us locked into multi year contracts. Anyone who’s at the end of your contract, run!

  • HowardYLAPE Howard Lee 🇺🇦 (@HowardYLAPE) reported

    @O2 It's now 2nd week down, only working sat/sun. My parents have been unable to do online banking (requires callback) , no texts etc etc. They are 80 & 100. Their phone/SIM don't do Wi-Fi calling and even if it did they're pensioners not techies.

    @EnglandRugby @O2 Sham 69 -.... We're all going down the pub....

  • cwinyork chris⇆sıɹɥɔ (@cwinyork) reported

    @daviddunninguk @O2 This has been a problem for years. You pay @O2 for a 5G phone and signal, but the data rate is so slow as to be worse than 2G. And absolute waste of time if you’re out and about in the city centre! 😡

  • bendougcraig Ben Craig (@bendougcraig) reported

    @ThreeUKSupport It’s pretty much everywhere. And yet people on other networks don’t seem to have the issues. And if I upgrade I’ll have to pay roaming fees. Unlike say @O2 So at the moment I see very little point in staying with you. You take my money and I get very little in return

  • lauries_mammy Sarah Willis (@lauries_mammy) reported

    @O2 are you having problems in NE29 area? Daughter has no data what so ever. Can only make phone calls?

  • PiCar100 Red Duck (@PiCar100) reported

    @O2 my nero voucher is shown being used but I have not used it this week? Could you please let me if there is an issue on your end or my app? Thanks

  • NormantonRegina Regina Normanton (@NormantonRegina) reported

    @O2 Reply 1of2 So after @O2 getting back to me on Twitter 👇 me taking the time to set out the whole debacle so they could help,they’ve responded to advise me to call their phone line number… the same number that I’ve rang 5 times and been promised a manager call back…

  • tracestarshine Tracy Allan (@tracestarshine) reported
