  • alexjbooks AlexJ (@alexjbooks) reported from Bristol, England

    @DPDgroup_news for over a week now you have held an iPhone 14 from @O2 and refuse to deliver it to me due to an error by o2 in the address. Neither of your companies customer service will take ownership. o2 simply tell lies. DPD put the phone down. WILL EITHER OF YOU SORT THIS?!

  • timefried Travis (@timefried) reported

    @O2 How did this improve your network coverage???

  • Intime42T TravelsIntime42 (@Intime42T) reported

    @O2 Many thanks, issues are reported with a mast. Do I need to just leave 02 and go with another provider if u can't get things fixed in a shorter timeframe than many weeks. I need to be able to use my phone. Thanks

  • TomElmer6 Tom Elmer (@TomElmer6) reported

    @O2 shame your network coverage is so awful in the UK though...

  • Just_Tambo Mr B.E (@Just_Tambo) reported

    @O2 Nar this is a joke… you’ve put me on your new 360 programme but failed to deliver my sim. I go to get a sim swap in store but can’t because your systems aren’t up to date. I spend hours (literally hrs) on the phone but just rings through! As a new customer this is TERRIBLE!

  • billh35 Bill Headley (@billh35) reported

    @MrKarlWilson @O2 Let’s see how long it takes. Good customer service is about exceeding the customer’s expectations.

  • Middleton_Ly Dr Lyndsey Middleton (@Middleton_Ly) reported

    @O2 Hi, I’ve sent a DM about a problem with an account that needs looking into. Can someone reply please?

  • kimbaslase Kim Slase (@kimbaslase) reported

    Trying not to be offended that @o2 customer service line literally hangs up on me every time I say what I need help with?

  • GordonComstock_ The Flying Aspidistra (@GordonComstock_) reported

    @TweetMRSGR @O2 Well... In some ways, at least they are preventing anyone from becoming new customers if this is how they handle their customer service.
