shocking service, airtime deducted and not returne

I upgraded my cellphone contract about two months ago. First problem-the phone that was meant to be delivered in 5-7 working days took 3 weeks!! No communication from Virgin Mobile's side at all. Problem 2-incorrect balances showing-I have been querying this for 2 weeks, no joy. Problem 3-money taken off airtime balance instead of off free minutes-escalated yesterday and feedback promised within 24hours-NO FEEDBACK GIVEN, NOT SORTED. Problem four-the worst service EVER from the call centre consultant and manager. Called to ask for feedback, didn't want to verify me so that he can help me, then told me someone will call me back with feedback, when I asked for a manager-I could hear the conversation between the manager and the consultant and it was clear the manager had NO interestin helping or even speaking to me. I eventually dropped the line.
