    @humour2457 @O2 Mines not working neither !! Can make phone calls but my 4g don’t work

  • marcoanastasi Marco Anastasi (@marcoanastasi) reported

    @O2 Extremely disappointed with customer service so far. Not fun to call four times and wait in a queue for an average of half an hour while on holiday - to eventually talk to someone who won't even believe that St Lucia is an actual country and that I should be able to get data here

  • claireka Claire Ault (@claireka) reported

    @O2 So I am paying for a service you are not providing and also did not warn me about the loss of. Are you providing me with the WiFi you are telling me to use?

  • MoonshineMishap Donna G (@MoonshineMishap) reported

    @NickCollinsPod @O2 Go to @VodafoneUK I've never had an issue with them and they actually help their customers

  • BordersBulbs Borders Bulbs (@BordersBulbs) reported

    @O2 I'm trying to get my old number transferred to my new sim. The old 1 is an original sized sim & I don't have a phone that takes it to get the PAC code. I've tried the online form which results in an email telling me to use the webchat which never works, please help

  • lionmanwb Wayne Berry (@lionmanwb) reported

    @O2 A bit patronising! It's clearly a network issue, why don't you try turning it off and on at your end

  • Gof1957 Gof (@Gof1957) reported

    @O2 Just moved to O2 by VirginMedia and installed Sim card but unable to login to MyO2 because account not activated. What do I need to do?

  • ShareZone5 Draft (@ShareZone5) reported

    @O2 CAN YOU CHECK YOUR DIRECT MESSAGES, JUST WASTED 1 HOUR ON YOUR CRAP ONLINE CHAT AND 1 HOUR WAITING FOR SOMEONE TO ANSWER YOUR PHONES.

  • lady_janeuk jane (@lady_janeuk) reported

    @O2 can someone please look at my dm as my phone has still not switched to o2 and I can’t get through on the phone to customer service

  • stephstwogirls Steph’s Two Girls (@stephstwogirls) reported

    @indigojo_uk Yep. SO frustrating! It's one reason why I have stuck with @O2 over the years though, and it's been worth paying more, because they have great customer service.
