  • JohnDWebb John Webb (@JohnDWebb) reported from London Colney, England

    @Stephen_Neal @O2 It’s the same with @NatWest_Help - their URL is ‘nwolb’ to login and check stuff. Surely these big companies should be leading by example?

    @O2 Still no response from O2 Customer Services. Please do not buy any products from this company

  • behu91 Ben (@behu91) reported from Hemel Hempstead, England

    @O2 are breaching trading standards. Have sent me a voucher code but are not allowing it to be redeemed against S21. Apparently due to being a new launch device, however there is nothing in the terms and conditions to suggest this should be an issue.

  • hiaw61 Robert Frame (@hiaw61) reported from Hatfield, England

    @O2 just to say that I have received a replacement phone which is a positive, however I hope they take this example of my frustration with their Customer Service in to consideration and keep their valued customer updated

  • MiaxKempster mia (@MiaxKempster) reported

    @O2 We tried that before I complained. We do have brains. He doesn’t have access to wifi when he’s out at work hence why he needs a working phone signal!!!

  • jusvegan Jas (@jusvegan) reported

    @O2 I bought a PAYG SIM card last year and have just realised it's exceeded the activation date. How do I go around activating the SIM? Can you help? Thanks

  • GeorginaDepree Georgina Depree (@GeorginaDepree) reported

    @O2 please be aware of fraud, anyone that’s been targeted by fraud by o2, a little heads up no one is willing to help the fraud team never ring back when they say they will, and your credit score could be affected because the company does not want to help!!

  • Angrybi66581358 Kaz 🇬🇧🇮🇱🇺🇲🇺🇦 (@Angrybi66581358) reported

    @O2 Using automated lines is not how to operate your company. Trying to find the answer was a nightmare, about time companies realised that we want to have a person at the end of a line not computer generated help lines

  • OyinSoExtra Oyin Baby• (@OyinSoExtra) reported

    I just want to know why @O2 isn’t letting me call and receive calls while I’m in Ireland! I’ve been stranded and put in very serious situations the past two days for some reason! I can’t even call customer service despite being able to roam. Wtf is going on??!
