    @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

  • 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

  • isthatdan Dan (@isthatdan) reported from Stevenage District, 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

  • 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

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

    @O2 Still no response from O2 Customer Services. Please do not buy any products from this company

Latest outage, problems and issue reports in social media:

  • talk_2_frank talk2️⃣frank (@talk_2_frank) reported

    @O2 no signal for o2 customers in LS2 8LX can you please advise?

  • DanielBreston Daniel Breston (@DanielBreston) reported

    @O2 I pity the people that you have migrated onto your new website platform. It is awful. It was created without considering the #customerexperience. It robs folks of things they used to be able to perform effortlessly.

  • JTU4EVA James (@JTU4EVA) reported

    I have no signal at all, what's wrong @O2 #O2Down

  • Ceris8 Ceris (@Ceris8) reported

    @O2 Finally, you are talking to me. Your customer service is appalling. This problem has been ongoing for several months now… Not being able to get access to the mast, landlord problems? This is unacceptable. @BWallaceMP

  • j13hb J. Silva📍🇬🇧 (@j13hb) reported

    @O2 It’s not happy Monday if my service is down fit the whole weekend

  • VModifiedMind Vince (@VModifiedMind) reported

    "If you're having the issue in multiple areas, it does lead us to believe that the issue is with your phone or sim" You have to love the nonsense @o2 comes up with. Yeah, because my SIM is why the data is crap in some areas. Or it's just that the o2 network is total garbage.

  • whi2001 Andy (@whi2001) reported

    Well @O2 I see you're keen to resolve the issue for me.

  • Ceris8 Ceris (@Ceris8) reported

    @O2 @BWallaceMP Smart meter doesn’t work ( don’t need that right now!). Why on earth is there an access problem?

  • 1daynearer ☆no.apologies☆ (@1daynearer) reported

    @O2 It's a weird coincidence then, happened more than once and if it keeps happening then I'll have to switch one provider because I need data if broadband is down. Seems ok today thanks. So, was there a problem yesterday? Because it was hours before it worked properly

  • JPWPhoenix John Wells (@JPWPhoenix) reported

    @virginmedia I recently got a Stream box but am unsure what I should do with my current subscriptions to Netflix and Disney+. I get the latter as part of my @o2 Pay Monthly contract. Do I need to cancel both services and then restart them on Stream? Please help!
