    Are all UK carriers going to sort out the poor VOLTE issue before you turn off 2 and 3G? Signal is there but calls frequently hang and the recipient of the call can not hear the caller. #4G #5G #poorcallquality @ThreeUK @O2 @VodafoneUK

  • AverellKaren Karen.Averell (@AverellKaren) reported

    @O2 Still waiting on a reply on helping 🙄 worst ever pay for an item upfront and no help when needed

  • BrianMa63080971 Brian Martin (@BrianMa63080971) reported

    Hey, @O2 - I have been asking you to resolve my issue for days now and you have done nothing - your customer service is an embarrassment. Why aren't you doing anything?

    @O2 Hi, I hold a samsung s22 ultra handset, I've had no internet on my phone today even though I was getting 5g reception, why is it that once I switched off the 5g and reverted back to 4g the internet started working again, What's the point of rolling out 5g if it's not working?

    @O2 You’ve been busier than usual on every single occasion I’ve got in touch with you since 2010, but you are perfectly happy to charge me for the privilege. Your customer service is worse than HMRC, that takes some doing, believe me

  • DayLafai DayLafai (@DayLafai) reported

    @O2 having literally 0 signal for weeks is a bit more than an inconvenience considering im paying for a service which you are not ptoviding.

    @O2 @Apple Bought watch never had apple fitness before the offer code didn’t work. Neither apple or O2 have been able to sort. Tried phoning today 3 times. Disconnected everytime. Very disappointed as bought for the offer! So much for meditation… stress more like

  • phizwald Sophia Kearney (@phizwald) reported

    @O2 having an absolute nightmare getting my phone delivered with you. Terrible way to start the contract. Need to speak to someone urgently today but I’m calling from three abroad and your abroad number on google doesn’t seem to be working how do I contact someone???

  • BrianMa63080971 Brian Martin (@BrianMa63080971) reported

    @O2 There has been no response - yesterday is not "earlier". WHY IS MY SERVICE DISCONNECTED WHEN O2 OWE ME MONEY? And please review the appalling call to O2 "customer services" - people like this agent should not be employed. RESTORE MY SERVICE!

    @hughesclaire39 @O2 Their customer service became awful when they merged with @virginmedia as they are bad.
