  • AddictiveColors Addictive Colors (@AddictiveColors) reported from London Colney, England

    @O2 I understand that carriages speed and materials do not help, but repeaters in tunnels sure would to avoid disruptions especially as they can particularly nasty to a laptop when the phone or the train is the hotspot as that side of the connection never goes down just the gateway’s

  • mrjc90 Josh (@mrjc90) reported from Hitchin, England

    @O2 not sure when your call centre in Cape Town opened but it’s been extremely painful trying to solve a simple issue..I might of been unlucky but think staff could do with some further training

  • 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?

  • hiaw61 Robert Frame (@hiaw61) reported from Hatfield, England

    @O2 absolutely APPALLING CUSTOMER SERVICE from O2 and would never recommend them to anyone. Unable to contact them and their phones just cut off and and unable to track anything on their website as again does not work. I will continue to post until they actually respond or call

  • hiaw61 Robert Frame (@hiaw61) reported from Hatfield, England

    @O2 just to say that I have received a replacement phone which is a positive, however I hope they take this example of my frustration with their Customer Service in to consideration and keep their valued customer updated

  • RaviDheer Ravi Dheer (@RaviDheer) reported from London Colney, England

    @O2 I'm sick to death of your network. I'm trying to pay you and I can't. Now I'll wait for some fool to contact me. I give up with this pathetic network.

  • dramattyhealy 🌜cobie🌛 (@dramattyhealy) reported from London Colney, England

    @O2 Hi, it’s been 2 weeks since i started receiving non stop calls from your call centres to get me get a plan with you, the caller said that i entered some kind of contest or signed up for this but i never did since i am happy with my current provider. This is very inconvenient

    @O2 I'm trying to get a refund for the account balance. Can't get on live chat. Can someone help?

  • Misschimpgirl1 Misschimpgirl (@Misschimpgirl1) reported

    @O2 I'm trying to transfer my number to you. I popped into an o2 store and they told me to call customer service. Even though it says on your website that the store can do it.

  • ijc1979 Ian Campbell (@ijc1979) reported

    This was @O2 mistake in allowing a fraudster to open an account and yet I'm the one being punished. Your fraud team do not seem to care. I even had to use a GDPR SAR to find out what the supposed debt was! I'm hoping you can finally help me to get this issue resolved.

  • Denirogers DENI ROGERS 🇬🇧 🇺🇦 🇪🇺 (@Denirogers) reported

    @thedogman_918 @ThreeUK @O2 You’re well out Chris, one of the few companies charging roaming again. They’ve let me down twice now when I was abroad. I’ll change when my contract comes up.

  • dharford79 Dave Harford (@dharford79) reported

    @thedogman_918 @ThreeUK @O2 There is no tears for loyalty anymore. I left three and was same crap service

  • Debbie90203616 Debbie (@Debbie90203616) reported

    @thedogman_918 @ThreeUK @O2 I’ve been with O2 for over 10 years and the last two calls received from them ended up with me getting a reduction in my monthly payment! They were seeing if I wanted an upgrade! So helpful and great signal always

  • JFlet41 Joni Fletcher (@JFlet41) reported

    @thedogman_918 @ThreeUK @O2 Rude!

  • JaniceS14628781 Janice Scott (@JaniceS14628781) reported

    @thedogman_918 @ThreeUK @O2 Aye when the bb is working. Thousands all over UK have had problems with that and intermittent wireless. Thank goodness we now have FTTD here now - neighbour has a Scottish provider for BB. They even outdo Virgin speeds and are at least £15 cheaper. Scottish Cust services too

  • Markrex70 Mark Rex (@Markrex70) reported

    @o2 how long is it acceptable to have a mast not functioning properly and yet you keep charging the same rate? For months I've had a sketchy 4g signal and the status page keeps saying another month for an update. Talk about naff service.

  • mrschappers1 Alison Chapman (@mrschappers1) reported

    @thedogman_918 @ThreeUK @O2 My eldest had a similar experience. It took him phoning to cancel to actually get a decent deal. Appalling customer service leading up to that
