  • Primrose_Hikwax Primmy💁🏾 (@Primrose_Hikwax) reported from Slough, England

    @O2 There was a mast down in my area but the matter wasn’t resolved for 3 weeks. I have data with EE on my ipad and the data wasn’t affected with them. With my phone I was unable to text, call or use my data. I don’t understand how you expect to put off £11, yet I haven’t been able

  • Peachey_79 Charlene (@Peachey_79) reported from Wandsworth, England

    @O2 Well after 3 phone calls and the staff in your Wandsworth store trying I was told I couldn’t cancel and had to wait.

  • RalphVarcoe Ralph Varcoe (@RalphVarcoe) reported from Merton, England

    @O2 Your own website says there’s a mast down. We had a problem quite a few weeks ago. Zero coverage makes o2 useless.

  • tanfish38 Tanya Fisher (@tanfish38) reported from Chesham Bois, England

    3rd day with no signal @O2 🤬

  • Peachey_79 Charlene (@Peachey_79) reported from Wandsworth, England

    Worse customer service @o2 I give up!

  • NHSNewey David Newey (@NHSNewey) reported from Croydon, England

    @o2 why is your 4g signal and internet bandwidth so appalling in Croydon. Pass through the town centre particularly through East Croydon and you might as well having no signal at all!

  • budgie Lee 'Budgie' Barnett (@budgie) reported from Paddington, England

    @O2 Wasn’t a problem, as such. ‘Kit breaks’ is an ever present rule. Was mainly to let others know,, if they had problems and wondered what was going on.

  • MikeBrownnutt Mike Brownnutt (@MikeBrownnutt) reported from Merton, England

    @O2 Just renewed with you for another 18 months. Your fantastic sales advisor informed me I’ve been a loyal customer for over 8 years. Any chance of sending me something to celebrate our partnership. 🍾🎉

  • MissPaulaGreen Paula (@MissPaulaGreen) reported from Camden Town, England

    @O2 I have noticed that the WiFi is not working in 2 locations today 👀🤨

  • depeare Steve Depeare (@depeare) reported from Ealing, England

    @O2 after 3 hours of calls 5 texts and 1:5 hours of to get family discount that is advertised and to be given an amount to pay then still getting it wrong . So a complaint to be made

  • oxymoron_tom Tom Bassett (@oxymoron_tom) reported from Wandsworth, England

    Is there a issue in the Earlsfield/Clapham Junction area, consistently been getting speeds of 0.01MB or no data at all @O2

  • davidchow David Chow 📶 (@davidchow) reported from Hammersmith, England

    @MIROFUR Disagree. In the UK it was an exclusive on @O2 as they built out EDGE and turned on support for interactive voicemail. It created a massive influx of people to the base, who continued to stay on even when the 3G version eventually shipped to other carriers.

  • KtHob Katie Hobden (@KtHob) reported from City of London, England

    Terrible customer service from @O2 who charged me £40 for data even though my data roaming was off #switchingtovodaphone #callingeverytimeigoabroadisnotpractical

  • Cla_Cottingham Claire Cottingham (@Cla_Cottingham) reported from Wandsworth, England

    @O2 Help. Unfortunately not which I now understand is not ideal!

  • RalphVarcoe Ralph Varcoe (@RalphVarcoe) reported from Merton, England

    @O2 Can you sort your mast out in Wimbledon please. Totally crap service for weeks and weeks and weeks. Really poor!

  • The_Lady_Jade_X Mrs Lady Jade ❤ (@The_Lady_Jade_X) reported from London, England

    Mother in law will deffo b leavin @O2 when her contracts up. She’s been abroad loads n never had issues. Goes Jamaica with new iPhone no issues. Goes to Europe with iPhone and no network. Apparently she needed to call them before n get a bolt. Load of rubbish! CS no help either!

  • jackaarondavies Jack Aaron Davies (@jackaarondavies) reported from Richmond, England

    @O2 Not everywhere, but your 4G coverage in SW London is poor. I haven’t had 4G in Raynes Park since I moved there a year ago.

  • MedinaMadam Eva Hamilton (@MedinaMadam) reported from Camberwell, England

    Not good customer service at all! Maybe you need to join me @O2

  • boogieloo Jodie De Vere (@boogieloo) reported from Southall, England

    @O2 I love @ O2 Customer Service

  • mattroy855 Matt (@mattroy855) reported

    @O2 35 mins waiting just to be cut off from your customer service line. No online chat other than that utter shite BOT. Disgraceful

  • PalmiraWorld Hello_World (@PalmiraWorld) reported

    @O2 What’s the point? I have always been told there is nonissues, but at the moment i am not even able to call the doctor cause the signal is weak

  • Dragon2611 Matthew (@Dragon2611) reported

    The number of alerts in the last couple weeks from @o2 and @VodafoneUK saying a mast is broken, it’s fixed , no wait it’s broken again

  • PalmiraWorld Hello_World (@PalmiraWorld) reported

    @O2 I have been reporting problems since end of 2019, but nothing has even been done! I cannot use the 5G in my house and the phone signal is awful and can only use the phone in 2 rooms and it now always working.

  • sjb002 Simon Billing (@sjb002) reported

    @O2 I will be looking this on your account as it’s stupid

  • tuimonkey Tui 🇵🇸 🌸 (@tuimonkey) reported

    @O2 @virginmedia We are not in a fibre area and the Virgin broadband checker doesn’t even recognise our postcode! The account is with O2. Absolutely appalling service as usual

  • tuimonkey Tui 🇵🇸 🌸 (@tuimonkey) reported

    @O2 Is there a broadband outage in the Gravesend Kent area? Day 2 of no internet!

  • KatyLeanne25 Katy P (@KatyLeanne25) reported

    @O2 horrible company! Scammed my husband into a contact with you by promising him you'd retrieve his voicemails of deceased relatives (which was a lie!) Then ruined his credit score (whilst trying to apply for a mortgage) saying he hasn't paid his contract when he cancelled it!

  • sjb002 Simon Billing (@sjb002) reported

    @O2 @O2 it’s unbelievable it’s a terrible service an hour waiting to spend money funny Apple answer virtually straight away meanwhile @O2 leave you holding for an hour

  • heth_neth Heath Netherton (@heth_neth) reported

    Want to buy a new phone, tried going in the shop and couldn't get seen, tried buying online repeatedly and there's errors and won't go through, tried calling the number the error message gave and it said it's not in use. I get it @O2, you don't want me and I'll find another place
