    Hello @dhlexpressuk - a parcel from @O2 has been lost in transit and I’ve been trying to get a replacement for a week (before going away on a solo trip for 3 weeks). Please can you help as I would like to take a fully functioning phone along with me. Thanks

    @O2 your signal is a joke. 5 places I have 4g and can't get anything to load. Wellingborough Kettering Markham vale Brackley I am sure there has been others but that's just today!!!

  • liane_wilce Liane Sara Wilce (@liane_wilce) reported

    @O2 just wanted to let you know the awful customer exp I had today with your team. 2 hours and 2 seperate phone calls passed from department to department and the result...a jiffy bag and a refund policy as you cant fulfil my order. Will be taking my business elsewhere !!!

  • KevinGibbins1 Kevin Gibbins (@KevinGibbins1) reported

    @Craigo71 @tescomobile @O2 New phone, 100Gb of data for £20 a month, 24 month contract, with 3. A couple of minor technical issues (mainly because I'm technically inept) which were sorted really quickly. Decent signal coverage. I was with Tesco but they couldn't match that.

  • snee_michael michael snee (@snee_michael) reported

    @O2 Hi can yon tell me if anyone is working in your fraud department? Been having an issue with someone opening an account in my name, been going on now for 5 months now and still not resolved, been ringing and emailing and still no further forward.

  • EHLFrost Emma Frost (@EHLFrost) reported

    @O2 won’t repair, replace or cancel my phone (without a 5 month fee) despite having bought phone from them & paying bill & insurance each month. Atrocious service.
