  • 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 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

  • 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

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

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

  • 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.

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

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

  • 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

  • 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?

  • 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

  • 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

  • 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

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

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

  • 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

  • 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.

  • dramattyhealy 🌜cobie🌛 (@dramattyhealy) reported from London Colney, England

    @O2 Hi, it’s been 2 weeks since i started receiving non stop calls from your call centres to get me get a plan with you, the caller said that i entered some kind of contest or signed up for this but i never did since i am happy with my current provider. This is very inconvenient

  • 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

Latest outage, problems and issue reports in social media:

  • gorners Phil Gornall (@gorners) reported

    Been with @o2 well over 10 years, whilst not the cheapest always felt value for money with the good overall service, price rises reasonable as per their T&Cs, but whichever idiot signed off a close to 12% annual ‘standard’ price rise at this time is either brain dead or sadistic

  • melwilks Mel Wilks 🏏💻☁️ (@melwilks) reported

    @O2 Been a customer 20 years. This is the end. I think your a disgrace.

  • melwilks Mel Wilks 🏏💻☁️ (@melwilks) reported

    @O2 Your network is terrible. Your 4G barely works in Devon. 3G if you’re lucky. No sign of 5G. So what exactly are you investing in other than your profits?!? No answer to either of my questions. I’ll be leaving at the first possible opportunity once your restrictive contract allows

  • LegendLarry_ Larry Laher (@LegendLarry_) reported

    @O2 @ben_pendery Have just sent a DM with my code as well. Attempting to use it in Leicester but again no luck. Can you help with this please.

  • hellfiregay Sylar (@hellfiregay) reported

    My mobile tariff is going up by nearly £2 in April - **** ******** off @O2

  • TheRealAMcKay Alastair McKay (@TheRealAMcKay) reported

    @O2 iPhone 5s Never used the app before now. Decided to use it to top up. Had to use the web instead.

  • _tbond Tom Bond (@_tbond) reported

    @O2 am at post code Mk43 0, your network bandwidth is shocking. Signal OK but never data transfer. Any plans to fix? If not, how do I leave? Watch on a 3-year, phone on 30-day. Many thanks!

  • mop_a_top Darren (@mop_a_top) reported

    @O2 Even this rediculous rise of almost 12%? New customer get the old rate too. Advertised prices don’t go up. It’s almost better value to use pay and go with a bundle (they don’t increase either it seems)

  • DuncanManton Felonius Dunc (@DuncanManton) reported

    @DarwinsWetDream @tsh2 @O2 They rise their prices by inflation plus a set percentage. Except the bill increase is a measure of inflation. Which they then add a set percentage to. Which drives up inflation. Which they then add a set percentage to… See the issue?

  • DandyBee Daniel Brennan (@DandyBee) reported

    FYI @O2, I suggest you consider using a service other than @dhlexpressuk, who, despite my three phone calls and their promises, have made absolutely no attempt at retrieving the phone they delivered to the wrong address last Friday.
