    @O2 why is your 4G so bloody awful at Liverpool Street Station

  • jodyrandall Jody Randall Esq. (@jodyrandall) reported from Walthamstow, England

    @O2 Please don’t tell me this mast is still not fixed. Again sat at Liverpool Streets Station with full service and 4G and nothing happening on phone full stop. Time to accept that coverage here is not good enough.

  • marcwhufc marc foley ⚒ (@marcwhufc) reported from Barnet, England

    @o2 your service has been shocking nearly 2 weeks and my daughters Apple Watch for Xmas not here. Now by all accounts best to start the order again as will be quicker and wait a week for deposit to be put back in my account 🤬 look at your dm’s I’m in them 2 replies so far 🙄

  • AlanGreene73 Alan Greene (@AlanGreene73) reported from London, England

    @StudiniJones @timlukejones @O2 Yep I thought the 13.3.2 update had fixed it but I’ve lost signal again this morning. Had to reboot my phone. I’m on latest update. Pissing me off now. People can’t call or message me until I’ve realised and turned phone off&on

  • Gigiryche Gianluigi PAGHI (@Gigiryche) reported from Harrow Weald, England

    Thank you @o2 for telling me now that you can’t solve my issue with @Apple Watch because “it is not a necessity device”. However when you publicised the deal “AppleWatch plus iPhone”, at the time of my purchase no one at the store mentioned “it’s not a necessity device”.

  • AddictiveColors Addictive Colors (@AddictiveColors) reported from London Colney, England

    @O2 I understand that carriages speed and materials do not help, but repeaters in tunnels sure would to avoid disruptions especially as they can particularly nasty to a laptop when the phone or the train is the hotspot as that side of the connection never goes down just the gateway’s

  • AEgbuonu ARIBBUZZ (@AEgbuonu) reported from Welwyn Garden City, England

    @O2 sort your cancellation team and phone problem out. #poorcustomerservice

  • AlanGreene73 Alan Greene (@AlanGreene73) reported from London, England

    @cleggytaxi @O2 Yep you’re right. Signal dropped again.

  • CerviF Fran (@CerviF) reported from Walthamstow, England

    I have just had a text from scammers pretending to be @O2 telling me there was a problem taking payment. They asked me to click on a link to confirm bank details. I didn’t. I deleted the text. Please RT and help others.

  • sarahcoysgabb sarah gabb (@sarahcoysgabb) reported from Broxbourne District, England

    @O2 Is incoming calls down as I have had so many missed calls from people who have had to call on landline not good for business

  • ColinShaw_CX Colin Shaw (@ColinShaw_CX) reported from London, England

    Unbelievable. I get a survey from @O2 regarding their service. I say it’s poor. They contact me and suggest a SIM card change. They have now cut me off until new SIM card arrives! For 3 days! O2 store can’t help. What a shambles! #cx #fail

  • BrianJThompson8 BrianJThompson8 (@BrianJThompson8) reported from Barnet, England

    @ItsAdsolution @O2 All of my calls which I've tried to make the O2 have not been answered I have a 40 phone and they don't seem to care I think if this keeps on we should see them because I've got a really bad disability and I've got a 40 phone so we should sue them

  • voottelecom VOOT (@voottelecom) reported

    @JamesMarriott @O2 🤔 that's very unusual. Definitely call O2 and ask. When we do business ports we usually get Sims that aren't live. The port happens on a set day and usually advised in advance. Strange they didn't issue a port date. Make sure they've not set up as a new number

  • shots_da DA_shots (@shots_da) reported

    @O2 I have had no signal all day - what’s going on???

  • siobhan_wright1 Siobhan Wright (@siobhan_wright1) reported

    @O2 We don’t always have access to WiFi so this tips aren’t very useful, I’m just wondering if you’re working to fix the problem and what the actual problem is?

  • 15shaan_ Shaan (@15shaan_) reported

    @O2 Never have I experienced a company like this they do not care about their existing customers all they do is Take Take Take

  • goblinshagger Pheel-it to the top please mate (@goblinshagger) reported

    @O2 told 6 times to cancel my order, promised it would be done yet here we are with a DPD delivery email

  • saj_anderson Stephen Anderson (@saj_anderson) reported

    @Doug_Paulley @ubereats_uk @O2 May I ask why your Claire Home have not taken the opportunity to set up some kind of mechanism to stop this problem from occurring? I know it is not their fault of course and know it isn’t the point.

  • ddbelle47 David Walker (@ddbelle47) reported

    @O2 Yes, Calls & texts are ok, but the issue must be more than the network being busy, as there are not that many people in these coastal resorts at present. It’s not BH yet and I’ve had 4 days with virtually no Internet. I wish to make a complaint 🤨

  • missscreenboo GEMMA BOND (@missscreenboo) reported

    @O2 Really unhappy with ky revent transfer to O2 for business .. have zero phone signal or Internet anywhere. I'm missing business calls and cant even call my voicemail to get messages. called into the store and they were VERY unhelpful or apologetic.. please advise

  • PalsyRon Ron Palsy (@PalsyRon) reported

    @O2 having issues - run out of data and myo2 wont let me add any data, its just a info box telling me I've recently changed my tarrif.

  • farleyamanda Farley (@farleyamanda) reported

    @BBCWatchdog @Ofcom O2 has shown an inability to deal with a simple contract change. I've been charged twice now for 2 services despite contacting @o2 for over a month before the switch. I've spent hours on phone to customer services & either been hung up on or had no follow up
