  • oliviakhwaja Olivia Khwaja (@oliviakhwaja) reported from Sunningdale, England

    @O2 great marketing activity. But no good doing that if you can’t provide basic service. Have been trying for 2 weeks to buy a new SIM. Passed around everywhere, 40 minute waits, given phone numbers by your South African call centre that don’t work. Not feeling like centre stage.

  • ShahlaaTahira 💟 (@ShahlaaTahira) reported from Hillingdon, England

    So now I’m without a phone and will never know where or what happened to my iPhone all because of poor customer service from Hassan in the @O2 Lewisham Branch! So much for customer service! #disgustedcustomer @BBCWatchdog

    @O2 have put up with terrible coverage for 14 months!! Promote 5G but I still can’t send a picture when on the commute in SELondon. Can’t wait for the contract to end. Worse provider I’ve experienced

  • JackCl1975 JAC (@JackCl1975) reported

    @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

  • BrianMa63080971 Brian Martin (@BrianMa63080971) reported

    @O2 BTW - worst "customer service" I have ever known - why are your agents so incompetent, sly, lazy, argumentative and arrogant? Start sacking some and training the rest properly.

  • KevConnor3 Kev Connor (Derby Toffee) (@KevConnor3) reported

    @virginmedia its actually mind blowing how bad you are. I've rang and complained, only to be transferred to @O2 . One way to deal with issues I suppose. A place in government awaits you...

  • Smart_Charlie4 CharlieBear🐻 (@Smart_Charlie4) reported

    Hi @O2. I recently upgraded my phone to another network and paid my final bill prior. You sent a rather threatening letter despite this. I have been charged £122.76 on top of my payment and when calling your paid CS number again for a refund, you send £4.22. Not happy please help

  • jvsingh .J ☬ (@jvsingh) reported

    @O2 Hello, this is now a big problem. I am not able to send or receive SMS from multiple non-UK numbers

  • SmallStocksJay Jace (@SmallStocksJay) reported

    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

  • SofieSokolowski Sofie (@SofieSokolowski) reported

    @O2 customer service is so so poor! Can’t get through on chat, phone number is impossible to find online and they don’t respond to complaints. Very upset new customer!

  • RamadhinRichard richard ramadhin (@RamadhinRichard) reported

    @O2 I have been complaining to o2 since November, multiple phone calls every month, still nothing has been done to resolve my problem, still waiting for a call back from customer service manager since December 22nd. Is this normal?

  • HBondgirl1965 H (@HBondgirl1965) reported

    @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

  • BrianMa63080971 Brian Martin (@BrianMa63080971) reported

    Hey, @O2 - WHY have you cut my service off when the Ombudsman has ordered you to pay me compensation? I am getting pretty sick of this and will continue to name and shame O2 for your lousy "service" until this is addressed. RESTORE MY SERVICE!
