    @O2 How did this shit happen

  • AddictiveColors Addictive Colors (@AddictiveColors) reported from London Colney, England

    @O2 I understand that carriages speed and materials do not help, but repeaters in tunnels sure would to avoid disruptions especially as they can particularly nasty to a laptop when the phone or the train is the hotspot as that side of the connection never goes down just the gateway’s

  • dramattyhealy 🌜cobie🌛 (@dramattyhealy) reported from London Colney, England

    @O2 Hi, it’s been 2 weeks since i started receiving non stop calls from your call centres to get me get a plan with you, the caller said that i entered some kind of contest or signed up for this but i never did since i am happy with my current provider. This is very inconvenient

    @Brian36989521 @O2 I still have nothing from o2 customer services after waiting 2 years & 4 months Worst customer services in the world

    @jimmy_lawrence @O2 Don’t hold your breath I still have nothing from o2 customer services after waiting 2 years & 4 months Worst customer services in the world

  • PaulBalanca Paul B. (@PaulBalanca) reported

    @O2 Customer service never disappoints. Constantly incompetent.

  • alpinoservices Alex Pino (@alpinoservices) reported from Fowey, England

    @O2 again us people in the PL23 postcode are abandoned to having no service. Your general “known issue at busy periods” is now wafer thin. For 6 months now, we will have no service. It’s stinks and I’m fed up with it. Sort it out or I’m off. For 3 years you’ve told us the same BS

  • _Bailo_ Bailoooooooo (@_Bailo_) reported

    @O2 Hi I’ve got data roaming on, changed my tariff to include USA and even though it says 4G on the signal bars I can’t use data. What can I do to fix it?

  • Faybee21 Fay Gibson (@Faybee21) reported

    @o2 @Geopost_news you were supposed to deliver my phone on Wednesday. It is now Saturday and the status is still delayed. I was told to go to the o2 store in Trafford centre. Their systems are migrating and only have half the customers details accessible wtf I just want to cancel

  • digitalfailure Brian Woods (@digitalfailure) reported

    @O2 Hey there! Can you tell me why your service is consistently woeful in Chester city Center (ch1) voice calls … when they work sound like a robot with a harmonica and 4G ….. yeah that old thing because you don’t have 5G yet… is slower than smoke signals. #shitchester

  • E2020Mc 💙⚡️💙Nic🏺⭐ (@E2020Mc) reported

    @O2 hi, my phone is not working can you please assist?

  • Jimbobthon James Richards (@Jimbobthon) reported

    Oh dear @O2 . Sitting in a café in the city centre of Cardiff. Barely a signal. @EE however, not only a signal but 125x + the speed on 4g alone. Please O2, stop saying "network is busy". Please stop saying "use WiFi calling". We don't pay for that. 1/2

  • TSTAR76535726 TSTAR (@TSTAR76535726) reported

    @O2 4g is as much uses as H+ shocking service considering I have full signal but nothing works.
