Double debit on contract

I app**** for an iPhone 6 contract online in September 2015 on the Telkom website.<br> <br> I was informed that an amount would be deducted from my bank account of R449 which is the contract installment. <br> <br> On the 23 September the amount of R449 was taken out of my bank account. <br> <br> The struggle thereafter started with me getting the phone. <br> <br> I only received the phone on 24 October 2015. <br> <br> I was billed for the month of October and November 2015. I called Telkom daily. I checked my bank account and was debited again on the 15th and 31st November 2015. <br> <br> My account again was debited on the 15 December 2015 and I now receive an sms that there will be another debit on the 31 December 2015. <br> <br> Help. No person who answers at Telkom customer service, can assist. Although they say they stop the second transaction, it still continues. <br> <br> I am very frustrated. <br> <br> I want the installment that was paid in September 2015, I sent two Emails to Telkom with proof of the transaction that the money was taken out. Still nothing. They say that they have stopped the double debit but it still continues.
