    Poor network in Se6 @O2

  • 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!!!

  • 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

  • ashley_leggett Ashley Leggett (@ashley_leggett) reported from Hounslow, England

    @O2 your signal in Hammersmith is a joke. London in 2021 and can’t even make a phone call.

  • 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

  • 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

  • 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).

  • 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

  • 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!

  • 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 👌🏻

  • 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!

  • 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.

  • 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

    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.

  • 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.

  • 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

  • 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

  • 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?

  • 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 🥳🥳🥳

  • 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.

  • stephenmc33 stephen mcloughlin (@stephenmc33) reported

    @O2 I’m just venting my anger about the so called pre order of the iphone 13 pro max I have received I ordered the handset 4 days before the actual release date Which on release date I never received I’ve been waiting a total of 12 days for my so-called pre-order part 2 coming

  • stephenmc33 stephen mcloughlin (@stephenmc33) reported

    @O2 I am at my tether getting passed from pillar to post off O2 customer service and the click and collect store any help would be appreciated as I have maybe 8 to 10 lines with O2 if this carries on I’m contemplating on cancelling and moving to a different network

  • AbaayoHeleey Dheex yar (@AbaayoHeleey) reported

    Im actually so excited to leave @O2 next month! A decade of terrible network and even worse customer service. Absolute joke.

  • StevenNT Steven Jones (@StevenNT) reported

    @o2 so my mum has had her phone cut off despite being on Direct Debit tried to call up but has had trouble getting it put back on. Can I have some assistance on her behalf? Thanks

  • theboylogan Steven (@theboylogan) reported

    @O2 can someone help me? I can't find a way to get in touch with you on your website. Puts people in circles !

  • jacksmith_ Jack Smith (@jacksmith_) reported

    @O2 Maybe you can cancel the order and I just go to the shop today and sign up again?

  • blacklight_ops Blacklight (@blacklight_ops) reported

    @O2 I run my own DNS over TLS service, and have been using it for ages. Now I can't access it from O2. I can get to it from other providers. And it seems O2 is intercepting all traffic on all ports.

  • michaelbeverla1 michael beverland 🦎🥝🎹🖤🦑🐙 (@michaelbeverla1) reported from Eltham, England

    @O2 just received new sim and trying to get it to work. Switched to you guys from EE but it will be the fastest cancellation in history at this rate. Your online help just isn’t

  • JenVonLee Jen (@JenVonLee) reported

    @McFadden1985 @O2 Absolutely. I had no intention of signing up to another lengthy contract, my old phone was just fine, not a days problem. But.. promises promises. Now I'm tied to another 3 years. Don't even get me started on the recent ipad debacle.
