    @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

  • 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!

  • AFCAMDEN AFCAMDEN (@AFCAMDEN) reported from London Colney, England

    @SkyNewsBreak Would cancel my contract with @O2 immediately if they did.

  • 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!

  • jodyrandall Jody Randall Esq. (@jodyrandall) reported from Broxbourne District, England

    @O2 why is your 4G so bloody awful at Liverpool Street Station

  • 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

  • sarahcoysgabb sarah gabb (@sarahcoysgabb) reported from Broxbourne District, England

  • 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

  • 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

  • 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.

  • 80__teresa Teresa (@80__teresa) reported

    @O2 I’m having horrendous customer service from you today. 4 times I’ve rang and been given different advice and still have a phone that can’t be used that was a Christmas present for my daughter! Can someone contact me please!

  • sjlewis Simon Lewis (@sjlewis) reported

    @O2 yes I have, but your contact/help pages are deliberately confusing and send users in a circular path around your website, get help > robot live chat > click here > get help > robot live chat... etc etc Try putting lost SIM into Aura & see what happens, doesn't need a discussion

  • BelleBeThere BelleBe (@BelleBeThere) reported

    @O2 Hello, I’m currently abroad in Mexico and I have connected to the device Movistar. The data won’t work despite me having the correct bolt ons and resetting my network settings I keep getting the error “could not activate mobile data network” please help

  • CashQuestions Annie Shaw (@CashQuestions) reported

    @YellowtailFP @O2 Have you got an O2 shop near you? I've just sorted out my broadband by calling into a high street shop rather than hanging on the phone and doing Option 1 and Option 2. You end up in the same place but with a face to face person accessing your account + dealing with your problem!

  • financialwalker Alasdair Walker (@financialwalker) reported

    @YellowtailFP @CashQuestions @O2 Telecoms companies are universally useless. My first job was an Orange shop, and it was awful then, and it hasn't got any better since! There is a "hidden" bolt-on that your rep forgot to add to your tarriff. It was the main reason for leaving o2, they struggle with iphone.

  • AlisonGillespie Alison Gillespie (@AlisonGillespie) reported

    @O2 bought 2 sim only contracts with the intention of adding on samsung watch plans to both. Got declined these a month ago and told to try again in 30 days and just got declined again. What is the point if offering watch plans when it's impossible to add them on? Awful service

  • m333ruu1 Umair Ahmed (@m333ruu1) reported

    @O2 I need help. Can anyone help me or is this the norm? Appalling customer service.

  • wordforwordguy Imran Bhai (@wordforwordguy) reported
