Telkom disastrous debit orders

I have been a telkom customer for 2 years now with no issues in terms of debit orders, i have never missed a single payment nor adjusted my payment dates, however this time around Telkom debited my bank account 7days later and not on the agreed debit order date, now I checked my upcoming May invoice and the figures were not making sense, i then decided to call customer care to get a breakdown of the next debit amount, but the response i got from the consultant is that I need to go read my contract terms and conditions and also contact my bank then he hung up on me.

So ya I am highly disappointed with Telkom customer service :(
