Unhappy Customer!

I am extremely unhappy with the service that Telkom has provided. I have recently switched banks. My bank has made contact with them since August for my debit switch. They refused to do so. I have tried contacting them to update my banking details. After having to go on there site and request a callback about 3 times in the month of September before my debits go off. I have tried requesting banking details so that I wouldn't miss a payment. I practically went out of my way to try to make payment. After almost a month of contact. The finally got back to me with an updated statement and accepting my debit switch. I now have to pay 3x my installment for October after because Telkom doesn't act fast! I honestly feel that they want customers to miss payments so they can pay high interest.

I am not happy at all!
