    @O2 why are the iPhone 12 deals better for a new customer than an existing long time o2 user? #absurd

  • T_Morris_Wealth Tim Morris (@T_Morris_Wealth) reported from London, England

    @emmahaslett @O2 Very good point. These things do tend to penalise the more vulnerable/worse off. I work with clients in the former category to help them become more tech savvy and keeping track of their finances. The latter don’t receive much support

  • MrsScreech Jess (@MrsScreech) reported from Hillingdon, England

    @O2 please sort out the broken mast in Yiewsley. Only having the capability to make WiFi calls from home for weeks on end is becoming frustrating!

    @O2 Trying to buy ‘Wicked’ tickets through the app, but I’m not receiving a code. Please can you help?

  • dresdeb Beccy Dresden (@dresdeb) reported

    Mobile reception has always been terrible at my house - pretty patchy all over MK - though @O2 keep insisting there's no issue. Currently I can't seem to received SMS (texts), which is a big problem for any service using that for authentication 😳 Anyone else experiencing this?

  • Edison7810 Ed Bell (@Edison7810) reported

    @O2 And if it's going to take 30 days to get a response why do your customer service advisors keep saying the fraud team will be in contact within 48h?

  • Treehk2 Treehk (@Treehk2) reported

    @Smeags842 @O2 Agree! Know this story and experienced it myself. Such terrible service. Log your report with Ombudsman.

  • itsamandared 🏰 (@itsamandared) reported

    @O2 Never! Someone told me this and no one had the ***** to say o2 made a mistake and I was charged more towards my device plan instead of my airtime plan! I spent 4 hours of my day for nothing.

  • janahaaa jane (@janahaaa) reported

    @O2 I have taken out a new SIM only contract. The new SIM hasn’t arrived but all signal has been cut from my current SIM? I need access to my phone when I’m out the house and don’t have wifi. Can this be rectified?

  • HiCatAteMyTweet hellokittyatemytweet (@HiCatAteMyTweet) reported

    @O2 hi I pay for my mum's Surfer Plan data on her ipad as she didn't have wifi. Now she has wifi she no longer needs the data. How can we cancel this? Can I just stop the direct debit? Thanks

  • funkytrampoline Emma Jones (@funkytrampoline) reported

    @O2 hi there, my pay as you go has suddenly stopped letting me send messages to some short code numbers for competitions. I have credit and it still lets me send them to some short codes. Please could you help?
