    @virginmedia since my virgin mobile UK signal has been shifted from piggyback Vodafone to @O2 it has been a complete disaster, constant signal dropping, constant WiFi calling cutting. This is before my account has been transferred to O2. Complete and utter rubbish

    @O2 @KLogan1977 Update: So @O2 asked me to DM details of the issue. I sent it hours ago, yet still no response. I wonder if there is an intention to help or it is an illusion of good customer service. Nor have I got promised call back after 22 hours from the CS phoneline. Not good!!

    @Aerial_Direct @O2 You play fast and loose with customer records and exploit trust. Shame on @o2 for a blatant breach of customer goodwill.

    @O2 repeatedly ignored by your dms.. been trying to contact you for days - I am incredibly distressed and humiliated by this treatment. Quick enough to get in contact when you want someone to sign up.. not so much when someone wants to cancel their account. Sort it out.

    @O2 I’m having problems sorting out the “extra” that came with my recent upgrade. Today is day 28, I need to choose today. Please help asap!
