    @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

  • mrjc90 Josh (@mrjc90) reported from Hitchin, England

    @O2 not sure when your call centre in Cape Town opened but it’s been extremely painful trying to solve a simple issue..I might of been unlucky but think staff could do with some further training

  • PaulWRamsay #HellomynameisPaul (@PaulWRamsay) reported from London Colney, England

    Really bad service from @O2, having calls from a shop to pressure into upgrades, no really clarity when calling 202 to ask what’s going on-I think I need a new network!

  • banafshbanafsh banafsheh (@banafshbanafsh) reported from Waltham Abbey, England

    @O2 customer services is shocking. What does a girl have to do to change ge a date of her bill 😕🤔#o2

  • h_123321x Me (@h_123321x) reported

    @O2 I’ve dm’d about your attempt to charge me £211.77 for a contract that has ended. Your customer services told me I would not be charged. Now I’m being harassed with emails saying the payment is overdue. Fix it! I want a call today because this is damaging my credit score.

  • SpannaD 💙🐝👑Spanna Monkey 🔧🐵🙊🏴‍☠️ (@SpannaD) reported

    @O2 Please help as my SIM card has been deactivated and I keep going round in circles to find a number to contact you on… it’s a pay as you go Thank you x

  • MFletch87 FLETCH #14 (@MFletch87) reported

    @O2 why does your automated service cut you off when you’re opening times are till 9pm... looking for a new contract

  • ndc140 Ndc140 (@ndc140) reported

    @O2 pathetic customer service. Don’t help your clients with your poor online content and every time you call you get stuck on hold for half hour then someone cuts you off. Disgrace network.

  • knobalob Sophie A 👸🏼 (@knobalob) reported

    Not had any @O2 signal for a few days now...

  • DHarbisher Dave Harbisher (@DHarbisher) reported

    @O2 Too late, my contract has been cancelled due to breach of contract by O2, definitely won't be a returning customer

  • bycandlelight27 BCL27 Design (@bycandlelight27) reported

    @O2 That's great, It has software and battery issues. I'm hoping I can just get a replacement one.

  • TravelBadger1 brock (@TravelBadger1) reported

    @O2 what on earth is going on with your network at the moment. I am being plagued suddenly with pfishing texts , another 5 reported today

  • pickled_tinker Ian Grody (@pickled_tinker) reported

    @Ofcom Yes, @O2 - take note. Having gone through every possible option on their customer services, you have to go to Lost/Stolen to actually speak to someone. Every other option hangs up on you.
