  • 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

  • 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 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

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

    @O2 Is incoming calls down as I have had so many missed calls from people who have had to call on landline not good for business

  • 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

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

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

  • AEgbuonu ARIBBUZZ (@AEgbuonu) reported from Welwyn Garden City, England

  • 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

  • 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.

  • Turtleflea1 Justin Smith (@Turtleflea1) reported

    @virginmedia @O2 As I said, you need to log on to engage with the forum: O cannot. Facebook and Insta can’t help, you own IT do not call back. How does one formally complain when I can’t email or log into my account?

  • jodenice Jo Russell (@jodenice) reported

    @O2 hi a little whilst ago I won some kind of treasure trail on the blue Mondays game. Said I would be contacted with details. But I never got it. Can you help please

  • bodge4uk Rob Lewis (@bodge4uk) reported

    @O2 still refuse to repair the network in Shrewsbury

  • Kcohen3103 kate cohen (@Kcohen3103) reported

    @O2 can you help? On priority I had a code which I tried to use but it didn’t work and now I have lost the code and the app says I have used it. Any help appreciated!

  • AndyWatson97 Andy Watson (@AndyWatson97) reported

    @virginmedia Yes and confirmation they’ve closed it ! Maybe it’s time to pass this to Offcom and let them deal as @virginmedia seem more bothered pushing @O2 SIM cards on everyone rather than fixing issues

  • charlotteisob Charlotte Isobelle (@charlotteisob) reported

    @TonyT0nes @O2 Yes. Although I decided in my wisdom it could be SIM card so got new one and put £10 credit on and not working still. But I did message them on insta and they said could take 5 working days for it to work, but I’m not holding my breath

  • TonyT0nes TonyTones (@TonyT0nes) reported

    @charlotteisob @O2 Nope. Still haven't heard back from o2. You got athe same problem?
