Handset Installment Fee Settlement

On the 06/10/2015 I called Vodacom because I wanted to settle the handset instalment fees ***2** and ***8**. The lady who helped me sent me the premature cancellation quotation and told me to pay the amount on section B (Equipment) and then circle that part and signed both forms. I transferred the required amount to settle the handset fee (R3300.06 and R1620.08). I sent the signed forms together with proof of payment to [Email Removed] I got an email stating that my email communication has been received ad the reference number was EC-0XM6-22CQT7. That was the last I heard from Vodacom with regards to this matter. I then called a couple of days and they told me that they received the amounts I transferred and that my handset instalment fees has been settled on those two numbers. <br> On the 25th there was no Vodacom debit order on my cheque account. I called today to find out why? they told me that I have a credit on my account and the R4920.14 that I paid to settle the handset instalment fees was used to pay for my last month's bill. <br> Please Vodacom rectify this mistake and use that amount I paid R4920.14 to settle the instalment fees on those 2 numbe
