Still charging me after nr shift to a new service

Virgin Mobile is still subtracting R99 / month for the number ***, after I moved my nr to a new service provider.<br> On 12 Feb 2015 I went to Cape Gate Virgin Mobile store and ask what I must do to when I want to move to a new service provider.<br> They informed me that I must come back on 2 March 2015 and then they will change my phone-contract to a pay-as you-go from 1 April 2015 and then I can change to a new service provider.<br> On 2 March 2015 I went to the Virgin Mobile shop. They worked on the computer and said to me that on 1 April 2015 my contract will be a pay-as-you-go and then I can go over to a new service provider.<br> On 1 April 2015 I took a new contract out with MTN on the nr ***.<br> I had several attempts to stop the R99/month to be deducted from my account, but with no success.<br> The one Virgin Mobile store personnel now informed me that they can not contact the financial department of Virgin Mobile and that I will never get my money back or get Virgin Mobile to stop deducting the R99 / month!!<br> Virgin Mobile owe me already 12 x R99 = R1 188<br> <br>
