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

  • J5752x Jay S. (@J5752x) reported from Paddington, England

    Went to @O2 #TCR to swap my monthly contract onto a prepaid card. I was told it has to be done over the phone and they can’t issue a new SIM in store. Went to @EE and asked if I could transfer my number to them. The seem enthusiastic

  • PatrickKeyte Patrick Keyte (@PatrickKeyte) reported from London, England

    @O2 please can you help me? Numerous people are getting calls from my mobile number when I haven’t actually called them or even have their details to start with. This has happened twice in the last week with two different people

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

    @EE following up on the bad signal in the area I now stay in, can’t even have a call while walking in the neighbourhood, I may have to make a drastic decision and move to @O2 I’m in a 12 month contract so what are the cancellation terms if you can not provide a reliable service?

  • AledSmith Aled Smith (@AledSmith) reported from Camden Town, England

    @O2 why is it so hard to get your systems to work properly. Don’t give me automated messages telling me I am overdue with my bill when I am not. Then sort out your customer support. How can your AI engine be too busy to ‘talk’ to customers. Rubbish.

  • TMytton90 Tom Mytton (@TMytton90) reported from Wandsworth, England

    @O2 had hardly any signal all week in SW16. No notification of works on the local masts. No impressed

  • hedaramusic hedara (@hedaramusic) reported from Hammersmith, England

    @O2 absolute JOKE of a service today. Got a deal offered to me by your retentions team TODAY, I ring back later to call it and no one with authorise it. Been passed to and fro for an hour and a half and got NOWHERE. The phone and deal I want is sat in my basket. Help.

  • des700 des (@des700) reported from Camberwell, England

    Hey @O2 ten year customer here, I have no data for 8 days after upgrading to unlimited data because I need data. I need data. What can be done? I will be looking for a solution elsewhere if you cannot help.

  • ninavdbennett Nina Van Driel (@ninavdbennett) reported from Windsor, England

    @O2 I am sorry but I am simply shocked at your poor customer service. I have now called twice to complain and ask for help. Twice I have been told a manager would call me. Twice this has not happened.

  • 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?

  • SteveHodgson1 Steve Hodgson (@SteveHodgson1) reported from Merton, England

    @O2 Hi, yes I’ve done both. Apps are so slow loading when wireless is switched off and service isn’t great on 3G or 4G. Used to be excellent

  • StephsBubble Stephanie Bennett (@StephsBubble) reported from Ealing, England

    @O2 Yes I’ve had the iPhone since the 3G and never had this before

  • AndrewCarrier Andrew Carrier 🍸 (@AndrewCarrier) reported from Hammersmith, England

    @cgledhill @McDonaldsUK @O2 I think the more pressing question is: Why are you using a public wi-fi network?

  • des700 des (@des700) reported from Camberwell, England

    @O2 I have no data. Have upgraded to unlimited but cannot add bolt ins until the upgrade arrives. Why? I need data for work. Please help

  • siegeism siege (@siegeism) reported from London, England

    @O2 Done. I’ve started taking screen shots of locations with no service because it’s so bad.

  • Mountie31 Ben Mitch 🇪🇺🏳️‍🌈🇨🇦🏴󠁧󠁢󠁷󠁬󠁳󠁿😎🤪 (@Mountie31) reported from Tottenham, England

    @O2 You have had this problem for the last 20 years doubt a self help guide will work. Ive made several complaints so end of contract I will be looking for a new service provider ...

  • daveya90 David (@daveya90) reported from Wandsworth, England

    @O2 just went into one of your stores to upgrade my phone and experienced the worst customer service. Was told to recycle my phone with another shop in the shopping centre and be without a phone for 3 days cause they’d “give me a better offer” and told I could shop online instead

  • StephsBubble Stephanie Bennett (@StephsBubble) reported from Ealing, England

    @O2 Yes I’ve had the iPhone since the 3G and never had this before - I’ve now tested on both front and rear cameras with and without HDR and it bleaches every time. Is the product faulty @AppleSupport or is this an iPhone 12 issue in general. How can I fix it?

  • depeare Steve Depeare (@depeare) reported from Ealing, England

    @O2 I’ve tried desperately trying to get hold of customer service and keep getting knocked off. I need a 5 g SIM card for my new iPhone 12 pro plus and need a 5 g sim , I think a card may be ordered but not the 5 g

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

    @O2 Thanks guys. Going to get someone I know with O2 to come through so I can check what your network coverage is like. Wife’s with @VodafoneUK and has no issues.

  • siegeism siege (@siegeism) reported from London, England

    @O2 after 13 years I’ll be leaving O2. The #reception literally doesn’t exist in South London, better service with a tin can and string. It gets worse year in year out. Are you erecting #phone masts underground or something?

  • hoarp001 Peter ***** (@hoarp001) reported

    @O2 I sent a letter about a week ago to cancel a new contract under 14 day cooling off period. I have not heard back. Your website will not give me contact details, it just goes round and round in circles. How can I get confirmation of my cancellation? Thanks

  • kllyflzn K e l l y ✌🏻 (@kllyflzn) reported

    @O2 Old number is Pay As You Go, never received any confirmation. I tried the form both ways, as one would keep sending me back to the homepage.

  • kmsarah90 Kmsarah90 (@kmsarah90) reported

    @O2 @Tizer42 This is a joke, not even available for an hour! I'm cancelling my contract and know lots of others who have said the same, it was the only thing keeping me with o2, nice weekly pick me up treat. Last week I went on Thursday and it was already sold out and now thus today!

  • mumofharry mumofharry (@mumofharry) reported

    @O2 Ive switched my mobile network to 02 from virgin when i try to text to another ipone they are not going through nor do i receive text messages from another iPhone

  • LilyPinkBaker 👻 Claire (@LilyPinkBaker) reported

    @O2 But how can I miss out? Surely the allocation should be enough for each customer to have one. And why is it now only once a month?

  • Carl_Hayward32 Carl (@Carl_Hayward32) reported

    Been back with @O2 a week & already been screwed over, 1st with the #O2Priority offer & then NO signal.Brilliant! #5Gisshit

  • wendyg4073 wendyg4073 (@wendyg4073) reported

    @O2 your service is shocking in Ayrshire again, sort it out!!!

  • steveprioruk Steve Prior (@steveprioruk) reported

    @O2 Hi. Have you got a problem with 4G in South Somerset? Can’t appear to get any data at all?

  • lynz84uk Lynsey (@lynz84uk) reported

    @O2 finding it very difficult to access help with My O2 account. My verification email expired and another link sent today hasn't worked. Your website keeps telling me to log in to My O2 for assistance - not much use when my issue is with logging in.

  • zeeshannadeem13 zee (@zeeshannadeem13) reported

    @O2 day 7 still no call back from a manger was told 24 to 48 hrs work hours way past that . Shocking customer service .
