virgin mobile fraudulent charges http://www.virginmobileusa.com/?cid=ppc_ybn_p_Bran virginia

I was charged #37.20 on July 21 b/c they wanted to change my phone when I got a new phone. I did not even get this plan b/c I wanted the pay-as-you-go plan that I already had.  They finally agreed , but then they charged me anyway.  They said they would refund my money within 10-14 days.  When I called on Aug 16, they said I had made 19 calls on that plan.  Then I was told 22 calls.  They refuse to refund my money b/c I used the phone with the plan on it.  Actually, I never used that plan.  Now they say they will add it to my balance, which is a total waste of money b/c I only use the phone a few times a month or for emergencies.  And I have never made 19 or 22 calls in one day.  If I go my bank and stop payment, they will cancel my phone.  So, they have ripped me off of almost $40.  Never ues this company.
