    @O2 @mtsavor I cannot call 202 or any other number that is supposed to be “o2” as I don’t know who I’m talking to. I’ve been hung up on twice when I’m explaining what’s happened. I need to cancel the iPhone contract or change the address with an actual o2 staff member!

    @O2 absolutely APPALLING CUSTOMER SERVICE from O2 and would never recommend them to anyone. Unable to contact them and their phones just cut off and and unable to track anything on their website as again does not work. I will continue to post until they actually respond or call

  • JohnDWebb John Webb (@JohnDWebb) reported from London Colney, England

    @Stephen_Neal @O2 It’s the same with @NatWest_Help - their URL is ‘nwolb’ to login and check stuff. Surely these big companies should be leading by example?

  • lordshaun_ Lord Shaun O’Brien (@lordshaun_) reported from St Albans, England

    @O2 customer services truly are as much use as an ashtray on a motorbike.

  • JanGoodeve Cllr Jan Goodeve (@JanGoodeve) reported from Hertfordshire, England

    @traceylsteve @O2 @GreggsOfficial I had the same issue in the #Hertford store, the app just said to try again later so ended up paying.

    @O2 are breaching trading standards. Have sent me a voucher code but are not allowing it to be redeemed against S21. Apparently due to being a new launch device, however there is nothing in the terms and conditions to suggest this should be an issue.

O2 Issues Reports

Latest outage, problems and issue reports in social media:

  • JC_CQ John Chambers (@JC_CQ) reported

    @O2 I've chatted to your less than impressive customer service team 4 times in 4 days regarding an issue moving a phone number to O2. Can someone contact me to resolve this please?

  • cjenscook Chris Cook (@cjenscook) reported

    Hello @O2 Is there any way of contacting you to increase my spend limit? The 8002 number is not working and the chat is busy? Since it's MY spend limit not yours, an increase within YOUR limit should not really require any human input should it?

  • scwjr Scott Worthington (@scwjr) reported

    @O2 is there a problem with the network at the moment? I can’t send text messages with out putting my phone on airplane mode then on again. Making calls sounds like I’m calling abroad! Help please

  • VictorMeldrew00 Victor Meldrew (@VictorMeldrew00) reported

    @O2 Nope it’s terrible, not helped that I moved over from ee. Gave you benefit of doubt due to mast issues, but no resolutions or timescales, most of the time phone unusable and im now outside the 14 day period - I can’t assess the service properly until it’s actually working.

  • bt4lor Brian Taylor (@bt4lor) reported

    Never ever leave @EE for @O2 ee may not be great but at least you get what you pay for, currently pay for phone service which @O2 don’t provide

  • FiveOhOneOh 5 ✪ 1 ✪ (@FiveOhOneOh) reported

    @rachelmcnamee @O2 it doesnt stop my life obviously but i have to restart my phone several times a day as "resetting" myself seems to... idk it puts you top of the queue or something as a recent connected device not sure how it works exactly but leaving yourself connected for days goes slow
