  • hcdw1988 Hannah (@hcdw1988) reported

    Hey @O2 it's been two months and my 4G is still unusable in my local town centre. I'm a pretty angry and disappointed new customer over here 😒

  • swailesfrmwales save the bees (@swailesfrmwales) reported

    @O2 your customer service is awful. Your inshore staff are lovely but useless. I was on hold for 45 mins only to be cut off. Your phone is shoddy and broken less than and year. @VodafoneUK @EE give me 5 more months of this **** show and I'll be in touch

  • AlisonGascoigne AFG (@AlisonGascoigne) reported

    @O2 URGENT, have reported fraud on my account twice, it’s my daughter’s phone. Both times told by your rep to cancel direct debit. Now get notice that account overdue and O2 have cut the calls and data. My daughter is travelling late tonight and cannot use her phone.

    @O2 What resolution??? I haven’t had an email from o2 since 18th May, and that was to advise I can activate my add ons, and a separate one to say I’m getting charged £125. So what the hell are you talking about??

  • Jimmy77uk James Adams (@Jimmy77uk) reported

    @O2 Problems on your website? Trying to upgrade but it's freaking out at the last stages and dropping everything out of my basket... Frustrating!

  • jamesldoyle James Doyle (@jamesldoyle) reported

    @O2 Thanks for the quick reply! Until the phone connects though, you have no visibility of which network you’re connected to. The signal went from Greece at the Airport/Transfer to Turkey at Hotel and even though I changed the network manually, it doesn’t seem right to be charged?

  • sonumatharu82 Sonu (@sonumatharu82) reported

    @O2 There doesn’t seem to be a complaints team. If there is, they definitely are not working!!

  • andyrennie Andy Rennie (@andyrennie) reported

    .@O2 it would be nice to have mobile service in Tq3 !!!! Once again let down, but as normal you will take your payment tomorrow 😡
