Account not credited as per agreement

<p>I took a contract with Telkom Mobile for iPhone 6 plus in October. So I was told for them to deliver the device to me they will have to deduct the full monthly payment of R449 which would be an amount I would have to pay in November. The pro-rata that was for October would be paid in November. On the statement I received on the 5th of November, an amount of R819.66 showed to be paid in November. I called the customer care and they told me an amount of R449 will be credited to my account and they will deduct the October pro-rata in November. I called Telkom Mobile customer care again on the 29th October to find out if they had sorted out my account and to my surprize they didn't. This meant that they would be deducting R819.66 from my account which they did on the 1st of December. Today the 5th of December I got a statement and the amount is still not credited on my account. Because Telkom Mobile refuses to credit my account I have decided that I would reverse the debit of R449 which was taken from my bank account before I received the phone.</p>
