    @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

    @O2 Please don’t tell me this mast is still not fixed. Again sat at Liverpool Streets Station with full service and 4G and nothing happening on phone full stop. Time to accept that coverage here is not good enough.

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

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

  • 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

  • uk_magma UK-MAGMA 🇬🇧 (@uk_magma) reported

    @O2 You want me to send you a PM so you can hide my complaint by taking the conversation private. Your robot customer service person will just highlight your current deals on Samsung and Apple crap which I am not interested in. Do you think I am stupid.
