  • hiaw61 Robert Frame (@hiaw61) reported from Hatfield, England

    @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

  • GoonerKJP Kaz 💋 (@GoonerKJP) reported from Stevenage District, England

    @O2 when I upgrade with a different network next week do I cancel my direct debit with you? Or do you do it ? @Barclays

  • 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

  • hiaw61 Robert Frame (@hiaw61) reported from Hatfield, England

    @O2 just to say that I have received a replacement phone which is a positive, however I hope they take this example of my frustration with their Customer Service in to consideration and keep their valued customer updated

  • 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

  • WickhamofWare Jonathan Flood (@WickhamofWare) reported from Stevenage District, England

    @O2 @tescomobile No mobile signal in Great Ashby, Stevenage all day!!

  • isthatdan Dan (@isthatdan) reported from Stevenage District, England

    @O2 are gonna have to either offer me an amazing deal or sort out this horrendous signal issue. How can I not load a twitter video when I have a full 4 bars of 4G signal

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

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

  • hiaw61 Robert Frame (@hiaw61) reported from Hatfield, England

    @O2 Still no response from O2 Customer Services. Please do not buy any products from this company

  • mrjc90 Josh (@mrjc90) reported from Hitchin, England

    @O2 not sure when your call centre in Cape Town opened but it’s been extremely painful trying to solve a simple issue..I might of been unlucky but think staff could do with some further training

  • 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?

  • 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.

  • AFCAMDEN AFCAMDEN (@AFCAMDEN) reported from London Colney, England

    @SkyNewsBreak Would cancel my contract with @O2 immediately if they did.

  • behu91 Ben (@behu91) reported from Hemel Hempstead, England

    @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.

  • GarethMcC7 Gareth McCarthy (@GarethMcC7) reported

    @O2 Already tried that. It didn’t help.

  • natasha_wainman Natasha Wainman (@natasha_wainman) reported

    @O2 hello, for a few days I have been having signal issues and I have checked online and it says a local phone mast isn’t working correctly in the NG17 area of Nottinghamshire. I was just wondering if you had any updates regarding this issue?

  • DianeBr81195108 Diane Brown (@DianeBr81195108) reported

    @O2 Have replied not sure it sent , but after no call yesterday today am told by the shop the credit appears to have got lost , funny that coz Customer services said yesterday no credit has been raised, my mother is blind and vulnerable , I want her money back today 02!

  • pdwill76 Paul Williams (@pdwill76) reported

    @O2 So what you're saying is that you can't get somebody to call me back? Can I ask why that's not possible? Out of interest, if I do call your "customer services" what's the current average wait time?

  • laurajademartin Laura Jade Martin (@laurajademartin) reported

    @O2 No problem! Luckily I don’t click on any links but wanted to raise the issue with you! Will report now!

  • DuncanMcCombe Duncan McCombe (@DuncanMcCombe) reported

    @O2 Thanks for sharing that, but it still doesn’t help me get to @TheAthleticUK and talk to somebody. I’ve been an O2 customer for 15 years and whilst I appreciate the problem is with a 3rd party it’s your name attached to it and I’m really disappointed.

  • special5757 sarah mustoe (@special5757) reported

    @O2 @GreggsOfficial can I use my priorities offer today at the store near the old Bailey? Last week my code wouldn’t accept through the till and staff wouldn’t allow me to use it until a l manager intervened. Don’t want the same issues again today if I can avoid it!

  • DuncanMcCombe Duncan McCombe (@DuncanMcCombe) reported

    @O2 @TheAthleticUK @TheAthleticMike Can you help?

  • Michael87384736 Michael Armstrong (@Michael87384736) reported

    @VodafoneUK Terrible service from Vodafone. Been a loyal customer for over 10yrs. Have four phone contracts with you. Mobile broadband has been useable since end of April. Going to OfCom now and will systematically move from Vodafone to @O2
