  • 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

  • ShanWilson_ Shan Wilson (@ShanWilson_) reported from Hemel Hempstead, England

    @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!

  • philter66 Phil Turner (@philter66) reported from Hatfield, England

    @O2 simply dreadful customer experience tonight -felt really let down

    @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

  • 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

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

    @O2 trying to upgrade on app and main website but when I choose it crashes can anyone help

  • 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?

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

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

  • juliet_gough juliet gough (@juliet_gough) reported from Stevenage District, England

  • HilaryRWriter Hilary Robertson (@HilaryRWriter) reported from Hitchin, England

    @O2 Yes. I’m trying to cancel my mobile broadband and cannot do it on myO2. The ‘help’ keeps sending me round in circles

  • lovepbx Pauline (@lovepbx) reported from Waltham Abbey, England

    @O2 I have been trying to talk someone ... please can someone get back to me! I need urgent help.

  • lovepbx Pauline (@lovepbx) reported from Waltham Abbey, England

    @O2 can someone from customer services contact me ... I need urgent help ... Thanks

  • 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.

  • 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

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

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

  • 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.

  • isobel748 Isobel Moore (@isobel748) reported

    @O2 I now haven't had working data or outgoing texts for over 6 weeks, with multiple phone calls and visits to the local o2 shop - waiting on a trouble ticket response but this is getting ridiculous! I really like o2 but sort it out....

  • Jopaco84 JoPaCo (@Jopaco84) reported

    @O2 are just ****. Absolutely ****. Placed an order on Friday and no one seems to know anything about it. They have credit checked me. And the only way to sort it is to sit on hold for ******* ever because none of their staff are allowed to message each other apparently. Shite.

  • Piglet11y Michelle Gilmore (@Piglet11y) reported

    @O2 how difficult can you make it for customers? Can’t cancel my contract online because it takes you round in circles and can’t cancel on the phone as it cuts you off saying to try again tomorrow, I’ve been trying for days!!! Can someone actually help me please?
