    @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

    @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

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

    @O2 are gonna have to either offer me an amazing deal or sort out this horrendous signal issue. How can I not load a twitter video when I have a full 4 bars of 4G signal

    @O2 Thirsty Thursday is not working again and no reply from direct message. Disappointing from O2 and a wasted journey

    @O2 For 2 years you've had a problem with a mast near me and need landlords permission of the land its on to fix it. You surely can't tell me that in 2years you haven't managed to gain agreement? Seems to me you should re-site the mast instead of you have this much trouble to go thru

  • tomross900 tomross900 (@tomross900) reported

    @O2 I complained to your customer service department that I was a victim of fraud on the 27th march. I was told your fraud department would call me within 3-5 working days.. wells it’s been nearly a month and no contact and now you want to restrict my contract due to no payment?!
