O2 Issues Reports Near Windsor, England

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

  • HarryRobertson5 Harry Robertson (@HarryRobertson5) reported from Bracknell, England

    @ThreeUK been a loyal customer for 6 years, recently brought a new contract through you, yet my upgrade price is far from being a loyal customer, I cant even get an existing customer deal unless I take out a third contract, what a joke! Even @O2 are cheaper than what I was told

  • HarryRobertson5 Harry Robertson (@HarryRobertson5) reported from Bracknell, England

    @ThreeUKSupport I want the note 20 4g but was told for 30gb £58 a month with a upfront cost, where as my "customer exclusive offer" was £55 a month. Or I can can to @O2 and get 90gb for £51 a month with a less up front cost. Talk about customer loyalty!!!

  • Jenzy84 Jenna Christie (@Jenzy84) reported from Wokingham, England

    @O2 sort out your customer services ! Waited ages and because the operator didn’t like me saying how ridiculous the service was he cut me off!!! #disgusted

  • 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.

  • SaintGeorgie Georgie Tongue (@SaintGeorgie) reported from Wokingham, England

    @O2 I spent hours on chat to your advisers trying to cancel my phone contract and was told it was all done. I started a new contract with another provider and now suddenly I have been started on a new o2 tariff??? Help!

  • Sheree_Kirby Sheree (@Sheree_Kirby) reported from London, England

    @O2 I have an issue with my phone, some calls are not coming through (not ring or notification if missed called) & I'm not getting voicemails till hours later, it's not updating. After the phone battery dies & switched on or restarted do they appear.

  • MissusWebb Sarah 🧡 (@MissusWebb) reported from Burnham, England

    @O2 I rang 202 and they said there was nothing they could do for me, just to change my password Will text that number now, thanks for your help 👌🏻

  • Kierbro Kieran Brown #FRSA 🏴󠁧󠁢󠁳󠁣󠁴󠁿🇪🇺🏳️‍🌈 (@Kierbro) reported from London, England

    @O2 I will! If you could sort out anything at all, that would be amazing...! I’ve been a loyal customer for more than 20 years so it would be much appreciated..!

  • carboncoach Dave Hampton 🌍 (@carboncoach) reported from Marlow Bottom, England

    @O2 Tried everything. (Apart from trying SIM in another phone). Previously if ever ‘SIM not working’ flashed up all I had to do was switch phone on/off. Not this time. Help!

  • 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

  • stevejonathan80 Steve (@stevejonathan80) reported from London, England

    Poor network in Se6 @O2

  • nickysinclair Nicky Sinclair PGA (@nickysinclair) reported from Windsor, England

    @O2 why are the iPhone 12 deals better for a new customer than an existing long time o2 user? #absurd

  • akasha303 Greg Meeres (@akasha303) reported from Twyford, England

    @O2 Your web chat support team advised I ‘needed’ to call Equifax, rather than Experian, even when I queried (as I have an Experian account). Might want to check the process playbooks! (Issue is now resolved through a work around).

  • musical_IH Iain Hunter (@musical_IH) reported from Spelthorne District, England

    @Br1tt3n @AppleSupport @O2 I’d imagine it’s more a network issue. My iPhone 12 Pro is gorgeous and hasn’t put a foot wrong

  • owengmusic Eoghan (@owengmusic) reported from Bracknell, England

    @o2 Ive transferred over to another network but I cant use my phone because you wont unlock it after 2 store visits (Wandsworth and Bracknell) very frustrating

  • 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.

  • carboncoach Dave Hampton 🌍 (@carboncoach) reported from Marlow Bottom, England

    My SIM only service with @O2 has packed up inexplicably today; and O2 slow to respond. Anyway I am without phone. So please DM if you need me.

  • carboncoach Dave Hampton 🌍 (@carboncoach) reported from Marlow Bottom, England

    If I was a shareholder in @O2 rather than a loyal customer today would be the day I sold.

  • MissusWebb Sarah 🧡 (@MissusWebb) reported from Burnham, England

    Hello @O2 I am back 🙌🏻 after a few years with no signal, awful service I have come back with my tail between my legs 🙈 #ohtohavesignal 🥳🥳🥳

  • 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?

  • Sarj007 Sarj Mistry (@Sarj007) reported

    @LeeMouse1 @O2 I've been told they don't have a Complaints or Payments department. Advisor very rude Asked to be transferred to a manager Last advisor had the nerve to say to me, 'it doesn't work like that, you'll have to wait 48 hours for a call back' Hello, I've been waiting 9 flipping days

  • stemag82 Stephen Maguire (@stemag82) reported

    @O2 Yep not receiving a message because o2 signal is horrendous.

  • AdamLiterally Λ D Λ M · (@AdamLiterally) reported

    @AbiBrooks @O2 Call O2 and put a password on your account if you don't have one. Someone did this to me and O2 forwarded my phone calls to a hackers number and they got into my bank account, and I had a password that they eventually guessed after 20 attempts and help from O2.

  • Hannah_Culley Hannah Culley (@Hannah_Culley) reported

    @O2 Hi, there must be an issue in the Swindon/Royal Wootton Bassett area, for over a month I’ve had terrible issues with signal and mobile data. What am I paying for if I constantly get no service and shoddy 3G? Can this be looked into please as not happy with what I’m paying for

  • duceydan Danny Duce (@duceydan) reported

    @O2 please help as the order has not arrived yet and no tracking info provided

  • _JacobDrew Jacob (@_JacobDrew) reported

    O2 have now hung up on me twice while I’ve asked about an upgrade. The most recent time is when I asked to speak to the management to complain. @O2 is this the sort of customer service you expect to give your long term customers???

  • Al_Vee_ Alexandra Hawkes (@Al_Vee_) reported

    @O2 I have now been without signal since Tuesday. I’ve been told it’s being fixed but still nothing. I’m unable to call/msg out unless I’m on wifi. It’s my lifeline as I’m bedbound most days. What is going on???

  • MandyGeorge12 Mandy George (@MandyGeorge12) reported

    @O2 I have been trying to contact you via live chat, WhatsApp messaging and my app for the last 3 days but no one has got back to me. I am without data on my phone and I need it urgently. I am extremely disappointed with your level of customer service.

  • lemoche_kr 김경수 (@lemoche_kr) reported

    @O2 Hi, finally my sim has arrived! Could you please help me to get the sim pack?

  • aljmurray Alastair Murray (@aljmurray) reported

    @O2 hi there, tweeting as requested - please could you check why the Priority/Apple Music sub offer isn’t working for me? Error message each time I try says there was a problem redeeming and to try again. Thanks!
