Debit Order

I made an arrangement with one of the collections agents I think it was on the 15July2015, I arranged for the debit order to go of on the 31July2015 for the amount of R1000.00 guess what my capfin bank account was debited yesterday 24 July2015 with the amount of R2100.00. I am very very upset with and this is not the first time this happened to me. I need that money to be reversed back to my capfin bank account because the bank its on my case requesting me to pay back the money because the is a capfin client that transfered the money into the incorrect bank account which is my capfin bank account. I did not instruct African bank agent to load the arrangement for the 24July, Can you please listen to your recordings regarding this matter because I'm really ****ed of with this kind of poor service as I told as well the the previous agent as well about the poor service that I got from the previous African bank agents. I feel not paying this account anymore so that you can take me to court maybe the court will help me much better than waisting my time and airtime sometimes to make an arrangement with African bank
