  • PaulWRamsay #HellomynameisPaul (@PaulWRamsay) reported from London Colney, England

    Really bad service from @O2, having calls from a shop to pressure into upgrades, no really clarity when calling 202 to ask what’s going on-I think I need a new 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

  • Kami2k10 Kamiioo (@Kami2k10) reported from Luton, England

    @BBCNews @O2 worst coverage ever no solutions. The network towers always down but yet I'm still paying 55£ p.m i have no choice but to pay!! #ripoffbritain #conmen

  • CraigFamilyBlog Hayley & Gavin (@CraigFamilyBlog) reported from St Albans, England

    Gav and I have had no mobile phone service for 3 days, but I have no service to call @virginmedia to let them know! It happens far too regularly. Just spent the morning searching for a new deal. @O2 looks like the best so far!

  • 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.

  • 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

  • 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 can’t you tell me why your customer service is so appalling called twice after I was given this number 034480490202 answer the questions and then Bye thanks for calling

  • 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

  • banafshbanafsh banafsheh (@banafshbanafsh) reported from Waltham Abbey, England

    @TazPDN @O2 So sorry to hear that ,#o2 is really bad, I'm with Vodaphone and they are much much better . Hope all get sorted for you x

O2 Issues Reports

Latest outage, problems and issue reports in social media:

  • ElisabethBowle8 Elisabeth Bowles (@ElisabethBowle8) reported

    After over an hour on hold to @O2 customer support for an issue that can only be dealt with via phone (and still no answer), I have decided to make my way to a shop and cancel all three of my contracts. I’ve been a customer for over 15 years. Disgraceful service levels #o2

  • Pozorovate2 Pozorovateľ (@Pozorovate2) reported

    @NomadicWriter @O2 I am so sorry this happened. Such fraud type is very popular unfortunately. The only solution is to interrupt incoming call immediately and call yourself to customer support directly explaining the situation because this could be either a scam or a real call from support also

  • DipityDip Emzy (@DipityDip) reported from Warkleigh, England

    @O2 hi I can’t get any signal in Christchurch Dorset is there a fault?

  • katiefitz_94 Katie Fitzpatrick (@katiefitz_94) reported

    I am appalled at O2’s customer service. I have been trying to have a fraudulent account taken off my credit file for several months now which is preventing me from getting a mortgage. O2 gave me written confirmation the account was closed and removed yet failed to do so. @O2

  • SzegfuSanya Sandorr Szegfu (@SzegfuSanya) reported

    @O2 It was sorted already. Customer service did something and I’m getting PayPal text again

  • grahbast Graham Bastock (@grahbast) reported

    @O2 My problem is still not resolved. I can't speak to a manager. Neither the old or new mobile work. After spending hours calling, at my expense, we are no further forward. I am not spending another 40 minutes waiting to get through after I have just been cut off.

  • RugbyThoughts12 GDRM (@RugbyThoughts12) reported

    Can anyone explain why O2 4G or even 5G for that matter is absolutely shite down South. I’ve had quicker 4G in the highlands of Scotland than down in Bath/Reading - takes 5 mins to load one website. @O2

  • RichardContardi Richard Contardi (@RichardContardi) reported

    @O2 Hi. Were trying to activate an extra on My O2 for Amazon Prime and we keep getting. 'We've encountered a problem. Please try again' after we got on the Amazon link

  • Jacedafaceis Jace Da Face (Blue TICK) (@Jacedafaceis) reported

    @Iversman I've been with @O2 for basically ever. But after that hike they can **** off. Soon as I'm out of contact I'm going rolling monthly like giff gaff or something.

  • olivia_bicknell olivia-jane' (@olivia_bicknell) reported

    @O2 I'm trying to add my O2 open discount and you're trying to tell me my work email isn't valid but it is my only work email?! How can I fix this?
