Stay away from these *******!

My account was in arrears so I wanted to pay in advance and called in before making the payment in order to get banking details and find out if by making the payment I would still get debited it not. The call center agent said I would not get debited because I was making the payment 10 days before the debit order request. I made a payment of R1824.92 on the 10th of November and on the 15th of November I was debited R1500, I had already requested my contract be cancelled which they have but they will not pay back my R1500 that was debited after I had settled my account. I have reported this to the NCC because from my experience Telkom makes a habit of *****ing from clients and they get away with it if you don’t complain.
