O2 Issues Reports Near Sunningdale, England

Latest outage, problems and issue reports in Sunningdale and nearby locations:

  • Stasisesque Lou 🐝 Lou (@Stasisesque) reported from London, England

    A tale of two CS agents. @O2 dealt with my issue and O2 Travel quickly and with excellent customer service. @Lustriga who has an IDENTICAL issue is being dismissed constantly and told it's his problem as the agent is refusing to read the conversation.

  • till_the_wheels 𝕵𝖚𝖌𝖘 (@till_the_wheels) reported from London, England

    @O2 @Joegreaney Hi I'd just like to add that this is a problem for everyone on 02 and giffgaff in that area and it's because a mast in hither green has been down for 2 years and these crooks hate you enough to ignore it.

  • natejrogers Nate Rogers (@natejrogers) reported from Wokingham, England

    So my @O2 contract has now gone back to its normal price (which is double). Does that mean I’m now going to get double the service? I bloody hope so, cos it’s pretty sucky at the moment.

  • Marcus_dd1 Marcus (@Marcus_dd1) reported from Southall, England

    @O2 Hi, my O2 cinema voucher keeps saying that there is a problem adding the voucher. Could you help me to go see James Bond tomorrow please

  • JdR_Tech Jacqueline de Rojas CBE (@JdR_Tech) reported from Taplow, England

    This Christmas, @O2 is donating data to those who need it. For every tweet using #O2DataPledge this Giving Tuesday, they'll donate even more data to the National Databank. Tap below to tweet your support 👇

  • ShaneyFirkins96 Shaney (@ShaneyFirkins96) reported from London, England

    @under_the_kilt @O2 I wouldve stuck with o2, Good luck with the limited Signal on Voxi 🤞🏻

  • ChristianRad Christian Radnedge (@ChristianRad) reported from London, England

    Something especially egregious about living near The O2, but not having any @O2 signal once again, even though that doesn't make sense. Feels like it should be a massive router for all of South East London...

  • DebsHaden Debbie Haden (@DebsHaden) reported from Slough, England

    @O2 I need somebody from your customer services team to contact me straight away! Your website is taking me round in circles and not helping. I should have had my contract cancelled and it hasn’t happened. So still paying out for it. Not happy at the moment.

  • SarahScogley Sarah cogley (@SarahScogley) reported from Bracknell, England

    @O2 your customer service is an absolute joke.

  • KellyMSanders kelly marie sanders (@KellyMSanders) reported from Bracknell, England

    @O2 hi I waited until the pro max was saying next day delivery to order - it says it right now so I paid my last phone off to order it and ten mins later got an out of stock email. Can you tell me how to cancel everything I just did please?

  • Stefan_baisden Baisden 📸🎥 (@Stefan_baisden) reported from Southall, England

    @O2 the phone has been cut twice from two separate convos. Will someone please call me back and tell me why my service has been down all day!?

  • EmlynAD Emlyn Akoto-Dwemoh (@EmlynAD) reported from Esher, England

    @O2 I was told a number would port over in 3-4 hours. 24 hours I am still waiting. Help please!?

  • LairdDourka Andrew Dourka-Laird (@LairdDourka) reported from London, England

  • amylouisestone Amy Stone (@amylouisestone) reported from London, England

    @O2 I have also been doing this too. If this problem persists, then what?

  • electriccandles ⚡️Emma⚡️ (@electriccandles) reported from London, England

    @O2 I've tried all that already. If I had WiFi access I wouldn't need the data to work. Phone signal works fine, just can't use anything with Internet. It's been like this for at least a month.

  • EmlynAD Emlyn Akoto-Dwemoh (@EmlynAD) reported from Esher, England

    @O2 Same network. PAYG to SIMO. I was told on the phone yesterday that it would take 3-4 hours. Not happy. 😔

  • Indian_Thriller Jeetesh Luhar (@Indian_Thriller) reported from Iver Heath, England

    Hey @O2 how do I cancel a SIM card that @virginmedia sent me as a data roaming replacement for the lack of WiFi installation service they’ve provided me at my new property? I wasn’t expecting to be charged extra for this mess up on their side so it’s a no thanks from me.

  • bedefeltham Bede Feltham 💙 (@bedefeltham) reported from Esher, England

    @O2 @gbuttars I'm trying to access Statements on MyO2 account as well. Says information not available at them moment. Is this part of the fix too? 🤔🙏 Please message here if so and once fixed....thx

  • Rochdale_Cowboy Craig (@Rochdale_Cowboy) reported from Maidenhead, England

    Took out an @O2 account as part of some 'volt' deal with @virginmedia. My god O2 are bad. Apparently you have to wait a few months to access your account online to wait until their systems "catch up" for new joiners. Shouldn't have bothered.

  • electriccandles ⚡️Emma⚡️ (@electriccandles) reported from London, England

    Idk what's going on with @O2 signal atm, but for the last few weeks I have no data signal around Crystal Palace at all. Doesn't come back till I get down to Sydenham. Weird

  • RyeBreth RB (@RyeBreth) reported

    @O2 don't follow through on their rewards when people sign up for new deals etc! Be aware that they make it ridiculously difficult to go through any customer care routes and don't respond to emails or call back when they say they will #AwfulCustomerService

  • AmeliaElton Emily Kay - Writer (@AmeliaElton) reported

    @O2 my partner took out a phone contact with you a few months ago and barely has had any signal unless he is at home connected to the WiFi. This is ridiculous, the phone is just a glorified calculator unless on WiFi. Should have stayed with EE.

  • sjmjarvis Sarah JM Jarvis (@sjmjarvis) reported

    @O2 Hi @O2. I have cancelled it now. I think perhaps this was part of the problem but the instructions really aren’t clear. I think the free period ran out either Sat or Sun. Just hoping I don’t get charged as cancelled this morning!

  • HeyStopItNow کودک (@HeyStopItNow) reported

    @O2 customer support is the worst I've ever encountered. Last 10 days, I have been trying to contact you and return the order. Once the agent started advertising SIM cards, I was paying for the call!!!! I have now been told that the deadline has passed. It's absurd @O2 !

  • TariyePeterside 💖 Tariyé 💖 (@TariyePeterside) reported

    @O2 what is wrong with your network today? I can barely make any calls and the one I managed got disconnected right when I was about to make progress

  • Trulyshocking Truly Shocking (@Trulyshocking) reported

    @o2 if my address with you is ‘ab12de’ but with @virginmedia it’s ‘ab1 2de’ Will this cause an issue with volt activation?

  • HalliwellDanny Danny Halliwell (@HalliwellDanny) reported

    @O2 @GoodThingsFdn @virginmedia Shame your customer retention isn’t so good

  • haslett_jeremy Jeremy Haslett (@haslett_jeremy) reported

    @O2 you are impossible to contact by phone, your email support is closed! Why are you trying to take over £500 out of my bank illegally? Contact me urgently! Thank you.

  • _riks_tweets_ Rik (@_riks_tweets_) reported

    @O2 I renewed my contract with you and instead of Disney+ I asked for o2 inclusive zone (available in US) I’m here and I can’t use my phone and I can’t contact you via support chat.

  • org_scp STOPCOMMONPASS ❌ (@org_scp) reported

    @9Esuzi @Telefonica_En @O2 No 404 on our end. It could be there browser or settings. Can you let us know if this is still an issue for them? Cheers.
