Taking my money twice

<p>I have cancelled my contract and received a cancellation quotation. I have had an amount of R110 to pay. On the quotation it stated only R82.50. 1st i paid the R82.50 then the amount of R27.50 was outstanding which i paid also the same day. I made this payment on the 11th July. I contacted Vodacom on the 12th July and they said they didnt receive my proof of payment. I have resend my mail as they asked. Again in August i contacted Vodacom and still they said they didnt receive anything from me. I have send the proof of payment again on the 15th August. Now today the 2nd September they went ahead and deducted that R82.50 from my account. When you phone Vodacom they say speak to cancellation department, but when you speak to them and you tell them the storry they say oh sorry speak to accounts department. I have also asked on my cancellation document not to make the sim prepaid and they went ahead and made it prepaid. When i spoke to accounts department this morning they said oh sorry but the R82.50 is for making the sim prepaid. I have contacted Vodacom 5 times this morning and everytime there is a new excuse. This is not acceptable, as i want my money back. </p>
