BILLING MY ACCOUNT

To whom it may concern:<br> My Monthly payments are R449.00 for 24 Months, however In February 2015 I was debited R1601.00????Then end of March 2015 R1539.00???and in April 2015 I was debited R593.00?? When I called the Call Centre a couple of times via 083 808 nobody answered my calls. Then I decided to go into the store in Tygervalley Mall in February 2015 and to the store in Canal walk in March 2015 and there I was advised that they will request a URL print out for me to see what I was charged so much for and received nothing up to date. <br> In February when I went into the Tygervalley store, Suzette - Branch Manager @ Tygeralley changed my open contract to prepaid and advised that this was effective immediately and it will also prevent any unauthorised debit amounts from going off my account. And then only to find that it happened in March and in April again.<br> I need to understand why all of this is happening
