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

  • 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.

  • 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!

  • 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.

  • 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

  • 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.

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

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

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

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

  • 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

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

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

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

  • 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...

  • 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!

  • 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.

  • 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

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

  • 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.

  • StyleMachineIl1 Style Machine Illustration (@StyleMachineIl1) reported

    @O2 ...they will be contacting me, allegedly, on Monday by which time I expect this disgraceful matter to be resolved. It has completely undermined my confidence in O2 as a service provider, and I am currently seriously considering taking my business elsewhere.

  • magso5 Magso (@magso5) reported

    @O2 how do I make a complaint?

  • AvmenC AVmen Construction (@AvmenC) reported

    @O2 Please get back to me to explain why you placed dmt on my credit file from 07.01.22? Chat does not work. No email to write to. I am in the queue on the phone for half an hour. No customer support lol

  • chsecsolutions CH Security (@chsecsolutions) reported

    @O2 Something's altered on your network over the last few weeks with customers reporting unable to access #CCTV systems except from on a #WifiNetwork It's been proven not to br a porting / system issue as other networks can still access the same system Please advise Thanks

  • Andrew14821367 Andrew (@Andrew14821367) reported

    @O2 why is your live char refusing to repair a device that I purchased less then 12 months ago, "because i no longer am an active customer". I made the purchase from o2 so you have legal duty to resolve.

  • birminghamb6 Shell (@birminghamb6) reported

    Had a little issue-ette with my new phone contract and have just had absolutely outstanding help from a lady called Kirsty and I think you should give her whatever customer service bonuses you might have internally @O2 And yes, it was user error 😳

  • Mandeep33303078 Mandeep Kaur (@Mandeep33303078) reported

    I hate to say this but after years of being an o2 customer I have never been so disappointed with the service I have received @o2 4 hours of my evening wasted trying to get help after losing my phone and still not resolved #alwaysbeenaloyalcustomer

  • DioneCrook Dione Crook (@DioneCrook) reported

    @O2 anyone else having service issues I have literally no access to any of my services and they were fine earlier today

  • magso5 Magso (@magso5) reported

    I've been with @O2 for as long as I've had a mobile phone, never had to contact customer service before this week and I have to say my experience has been nothing short of appalling. #o2
