    @O2 I need to escalate a complaint re. a member of staff who refuses to to 1) process my upgrade and 2) who has just terminated my call. Who can I talk to? Your staff say it’s not possible to talk to a manager.

  • gareth_thmpsn Gareth Thompson (@gareth_thmpsn) reported from Belfast, Northern Ireland

  • jennika28 Jennifer Brown (@jennika28) reported from Maghull, England

    Please @O2 can you fix this now

  • Nacnan1873 Nacnan (@Nacnan1873) reported

    @O2 How about delivering the Apple Watch I ordered nearly 7 weeks ago absolutely shocking service and absolutely no communication 😡

  • ace_7744 Michelle Price (@ace_7744) reported

    @JefferyBeaker @O2 @virginmedia I have the same problem, can't do anything that requires online connectivity. Keep getting the same replies off them. Virgin media sucks 😕

  • lewisbyers92 Lewis Byers (@lewisbyers92) reported

    @DisneyPlusUK I recently took a contract with @O2 and got 3mo free. However now that’s ended and I pay Disney via my o2 bill. How can I swap back to being a direct Disney customer as I’d rather refer the 2 aren’t tied together

  • naffynathan Nathan Everitt (@naffynathan) reported

    .@SkyHelpTeam So no broadband or 3/4/5G in Great Yarmouth area. Resorted to texting family members to find out information. Your website - nothing. @O2’s website actually says there is a mobile issue, yet yours doeen’t! Your customer service was pathetic over the phone.

  • jennika28 Jennifer Brown (@jennika28) reported from Maghull, England

    @O2 I think you have turned my sim off before a new one has arrived. I need to be able to use this one now. Please fix asap so I can sort my medical issues. I have private messaged you but had no reply

  • JefferyBeaker Steph Merry (@JefferyBeaker) reported

    @virginmedia It isn’t known. Staff have said there is no problem but then have also ‘fixed’ problems over the phone several times with no change. We just want an engineer to come and change the receiver but get fobbed off. You and @O2 need to up your game. Still take the money each month.

  • CornwallHour Cornwall Hour (@CornwallHour) reported

    Apologies my Internet keeps dropping down .....the tweets are sporadic...anyone else having @O2 signal problems Penzance area? #cornwallhour

  • Staceyc25701006 Stacey clark (@Staceyc25701006) reported

    @O2 @O2 costings for so called mobile data use - data disabled - over £145 over two days! So called correct cos out of Europe yet it’s taken 4 days and still no response from customer services -always try later as you are busy!!! #ripoff #nocustomerservice #mobiledata

  • EyeEdinburgh Jane Carnall (@EyeEdinburgh) reported

    @O2 How it feels when @O2 won't fix the problem, won't say how long it will take to fix the problem, & won't respond to queries about the problem. Seriously, is this one of those caseswhere you have to leave to get to speak to someone?
