    @O2 I need somebody from your customer services team to contact me straight away! Your website is taking me round in circles and not helping. I should have had my contract cancelled and it hasn’t happened. So still paying out for it. Not happy at the moment.

    @O2 @Joegreaney Hi I'd just like to add that this is a problem for everyone on 02 and giffgaff in that area and it's because a mast in hither green has been down for 2 years and these crooks hate you enough to ignore it.

  • Mountie31 Ben Mitch 🇪🇺🏳️‍🌈🇨🇦🏴󠁧󠁢󠁷󠁬󠁳󠁿😎🤪 (@Mountie31) reported from Hounslow, England

    @O2 Phone masts are down at my work and home so not good.

  • ShaneyFirkins96 Shaney (@ShaneyFirkins96) reported from London, England

    @under_the_kilt @O2 I wouldve stuck with o2, Good luck with the limited Signal on Voxi 🤞🏻

  • timnisbet tim nisbet (@timnisbet) reported from Hazlemere, England

    The is very cathartic after 25 years with @O2 I’ve left for @VodafoneGroup the o2 customer care and support is utterly woeful. And having given them so many chances I’ve had enough, so over to you vodaphone can you step up

  • amylouisestone Amy Stone (@amylouisestone) reported from London, England

    @O2 I have also been doing this too. If this problem persists, then what?

  • GAdams_Spink Geoff Adams-Spink (@GAdams_Spink) reported from Harrow Weald, England

    So, @O2 is complicit in this rip off but unprepared to do anything to assist a long standing customer.

  • natejrogers Nate Rogers (@natejrogers) reported from Wokingham, England

    So my @O2 contract has now gone back to its normal price (which is double). Does that mean I’m now going to get double the service? I bloody hope so, cos it’s pretty sucky at the moment.

  • ChristianRad Christian Radnedge (@ChristianRad) reported from London, England

    Something especially egregious about living near The O2, but not having any @O2 signal once again, even though that doesn't make sense. Feels like it should be a massive router for all of South East London...

  • SarahScogley Sarah cogley (@SarahScogley) reported from Bracknell, England

    @O2 your customer service is an absolute joke.

  • alexnovicov alexander novicov (@alexnovicov) reported

    @O2 do you have network issues today? My mobile data stopped working

  • cneillstweet Chris Neill (@cneillstweet) reported

    @O2 O2 is already providing unforgettable moments here with a hacked account and zero contact from O2 fraud team in over a month now. Absolutely terrible service and we are talking about illegal activity on the O2 network here. @Ofcom are you investigating O2’s lack of fraud response

  • Antibac5 2Legit2Quit (@Antibac5) reported

    @O2 @skytv why is both networks not loading anything. As soon as the weather turns bad boom. Are we still at dialup speeds because it feels like it is.

  • TheVirtualPanda Panda (@TheVirtualPanda) reported

    @O2 Your customer service is shockingly bad. Trying to get an issue resolved over live chat and the rep's are clueless and don't listen to what you tell them. And only advice they can give is to visit an O2 store, which is hardly good advice given the current Omicron wave.

  • arandombadger Jamie McEwan (@arandombadger) reported

    Dear @O2, your voice IVR is a honking piece of ****. Please bin it.
