    Does any service actually do what it says anymore without me having to check, ring in & find out what’s going on? Changing SIM provider to @O2 activated SIM 4 days ago & number still not ported over & now told won’t be until Monday. Info says 1 day.Fed up of juggling SIM cards.

    @Nicola_M91 @O2 Like everything else with @o2 nothing works #signal

  • SimonLebeau7 Simon Lebeau (@SimonLebeau7) reported

    @O2 have the absolute worst customer service. They’re rude, belligerent and have an amazing nack to screw up completely and blame the customer and then do absolutely nothing to fix their error.

  • Rubbertoe1983 LifeInSlowMotion (@Rubbertoe1983) reported

    @O2 Not successful due to your app being down to anyone other than ticket bots which you have done nothing to prevent. You have seriously embarrassed yourselves. Blaming customers for demand is pure gaslighting. The app was down for 24 hours due to your **** up

  • JoshCrook97 Josh Crook (@JoshCrook97) reported

    @O2 Unbelievable shambles and wasted my morning trying to get through your broken app. I cannot believe you would underestimate the demand so poorly considering Peter Kay’s popularity and how his return has made national news

  • jimmyhall Jimmy Hall (@jimmyhall) reported

    Come on @O2. Been a customer of 20+ years. Spoke to retentions today to upgrade my phone. They gave me a price. I then called back this afternoon to proceed, only to be told the price had gone up! ‘No notes on the system’. Poor form! #paccodeplease

    @idlewildgirl @O2 O2 sucks badways, moved our corporate account from Vodafone and I can’t even refresh a webpage on ‘5G’ in a city centre

  • Secretdemon1 Secret demon (@Secretdemon1) reported

    @O2 What @O2 means to say is that their system has failed terribly and they have the worst systems on place. Oh yeah and there a con.

  • Hayles7389 Hayley Falconer (@Hayles7389) reported

    @O2 How!?! Are you having a laugh at your genuine fans and customer's expense!? The site and app hasn't been accessible at all yet you've sold out presale! What an absolute joke, a complete and utter shambles!!!
