  • 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

  • PaulWRamsay #HellomynameisPaul (@PaulWRamsay) reported from London Colney, England

    Really bad service from @O2, having calls from a shop to pressure into upgrades, no really clarity when calling 202 to ask what’s going on-I think I need a new network!

  • 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

  • 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

  • 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

  • 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

  • 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

  • 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

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

    @O2 I have an enquiry and can’t find an answer on the ‘My O2’ page. Please help. #CustomerService #o2

  • angeliz35 Carmen Hobbs (@angeliz35) reported

    @O2 the signal in the DN8 4 area is non existent. You think a £30 credit and telling me to turn off certain things on my phone that I'm paying for will help. Guess what .... It didn't?!! I can't make or receive calls and it's diabolical

  • MinalCEO Minal (@MinalCEO) reported

    I need to make a landline call asap @O2 why tf is the network down?

  • angetilley Angela Tilley (@angetilley) reported

    @O2 What is going on with customer services, I've been trying for weeks now to get an issue sorted??!! Very much regretting moving to O2 & will not be staying quiet if anyone wants to know how O2 operate - so frustrated!

  • Ossyref Paul Bell (@Ossyref) reported from Great Harwood, England

    @O2 Thanks. That’s a bit poor though really. There’s no need for me to talk to anybody I just want to pay it off. #useless

  • tbowden1960 Tom Bowden (@tbowden1960) reported

    @O2 dear Lord I cannot believe how difficult it is to ‘port’ to your network - interestingly billing seems to work OK

  • Anthony15665779 MCFCANT88 (@Anthony15665779) reported

    @AnnaJBradshaw @O2 Yes mines been down for 3 weeks nearly and O2 customer services are useless when talking with them as they keep ßying it's to do with a mast in my area.

  • freemotely Ben (@freemotely) reported

  • shaunll0001 Ⓢⓗⓐⓤⓝ Ⓛⓛⓞⓨⓓ (@shaunll0001) reported

    Odd that @O2 can't help with a cancelling a contract in store and I have to call 🙄

  • NicholasDan1el Nick Ford (@NicholasDan1el) reported

    @O2 Why is it taking two weeks to deliver my new phone? I can see these phones in the O2 shops - and in other shops. I literally am now left without a phones for two weeks as I'm upgrading to replace a broken phone. It's such a hassle.
