Latest outage, problems and issue reports in London Colney and nearby locations:

  • EmJen81 Matthew J (@EmJen81) reported from Dunstable, England

    @O2 Why, for the past 6 months can I STILL not upgrade my phone online or any of your stores due to your dire lack of stock. I've had this phone for 3 years and it's dying. Yet you never seem to have any stock. Other networks aren't having issues!? Time to switch perhaps.

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

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

  • DrHannahLB Hannah Lomax-Browne (@DrHannahLB) reported from Walthamstow, England

    @O2 I don’t know what I’m paying for? Unless I’m somewhere with WiFi I have the worst internet, anywhere I go! I’ve tried all the steps to fix and still terrible internet. Unacceptable!

  • 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...

  • monicathenurse Monica, BSN, RN, MFCI (@monicathenurse) reported from Walthamstow, England

    @O2 hi I called customer service but they can't find my account I want to give notice to cancel my contract.

  • 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.

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

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

  • ElaineHenesy1 Elaine Sheppard (@ElaineHenesy1) reported from Watford, England

    @O2 disgraceful customer service had my account hacked ,o2 have admitted fraud on the account. O2 are now not refunding the £500 .Terrible service from a company I have been with over 20 years.#o2 #fraud

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

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

  • lordshaun_ Lord Shaun O’Brien (@lordshaun_) reported from St Albans, England

    @O2 customer services truly are as much use as an ashtray on a motorbike.

  • sarahspoon Sarah (@sarahspoon) reported from London, England

    @JamesIMcKay @O2 Oh….never heard of it. Ta

  • 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!

  • ian_slade2 Ian Slade (@ian_slade2) reported from London Colney, England

    @O2 is the data network down? Zero mobile data connectivity all day. Plenty left on the plan

  • Mattoco Matt O'Connor (@Mattoco) reported from St Albans, 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 👇

  • julie_virgo1 julie virgo (@julie_virgo1) reported from Croxley Green, England

    @O2 #02priority can't seem to get a code for hairspray.. Can you help? 😲

  • 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.

  • T_Morris_Wealth Tim Morris (@T_Morris_Wealth) reported from London, England

    @emmahaslett @O2 Very good point. These things do tend to penalise the more vulnerable/worse off. I work with clients in the former category to help them become more tech savvy and keeping track of their finances. The latter don’t receive much support

  • GAdams_Spink Geoff Adams-Spink (@GAdams_Spink) reported from Harrow Weald, England

    So, @O2 is complicit in this rip off but unprepared to do anything to assist a long standing customer.

  • arigork Ari Gork (@arigork) reported from Barnet, England

    @O2 Fixed the issue. Turned Volte off, rebooted, turned back on and got wifi calling back :)

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

  • Deanerobinson Deane Robinson (@Deanerobinson) reported

    @O2 Disney plus extra for £5.99 per month still not working. Constantly get error message saying oops there’s been a problem

  • iamhafiz91 Mohammed Hafiz (@iamhafiz91) reported

    @O2 can not believe how bad your data/network is. Can’t connect to the internet when outside. Whats the point in having 120gb when I’m only able to use like 5gb in a month. Get it fixed

  • JusticeBenson JUSTICE 🇳🇬🇬🇧 (@JusticeBenson) reported

    @O2 I'm still waiting for a call back. This is why I am shocked at how @O2 treat customers that pay their bills IN ADVANCE. 😑

  • Gorman1988 Rob Knight © (@Gorman1988) reported

    Well after being with @O2 for as long as I can remember, I have finally ****** them off today! There service has been absolutely abysmal over the last few months, no signal, no 4G, no updates on why or what was being done to rectify! Customer service just as bad too! Bye bye 👋🏻

  • Saltnpepper4eva Joseph Kelly (@Saltnpepper4eva) reported

    @O2 @Indian_Thriller I’ve been waiting for a response since Wednesday. One of your advisors sent out a replacement sim to troubleshoot poor network access, and blocked my current sim without telling me.

  • Age_of_Aquarius Type That Talk… (@Age_of_Aquarius) reported

    @O2, outside of my house my data works perfectly fine. Why am I having issues whilst in my house where I have @Virgin internet service? I prefer to use my data in home as I pay enough for it and also because Virgin’s internet is straight garbage. Fix it!

  • Sergio_FeGu Sergio Fernandez (@Sergio_FeGu) reported

    @O2 hi, I have been with O2 for more than a week, my Volt benefits are already applied in my broadband but not in my data allowance. Is there any way to check if there is a problem with my address to get it applied too?

  • appccessible Kevin Mc (@appccessible) reported

    Since @libertyglobal got their hands on @O2 things have really gone down hill for customers. #5GAt3GSpeeds

  • SiGarner1 Simon (@SiGarner1) reported

    @O2 are there any issues with your network? I can only get a 3G signal, inside and outside the house - I’ve tried turning my phone off and on and data off an on with no luck

  • nahemsworth Nicky (@nahemsworth) reported

    @O2. No data signal at my home despite showing 4G. Please will you arrange for somebody to come fix the mast and refund me the costs for not being able to hotspot to work from home!!
