Absa just run debit orders when ever they feel lik

I have a personal loan with absa and had fallen behind on payments. By the end of the term(December) I was four payments behind(plus interest). I phoned and made arrangements with them. A day after I made the arrangents they went and ran a debit order for a full mothly premium regardless of the arrangement. In January I deposited money into my account for other debit orders and Absa ran another debitorder as soon as the deposit was made. I then borrowed money from my mom to put into my account as my car premium was one of the debit orders that was suppose to go of. And AGAIN they ran another debit order. I then phoned them and they reversed one premium. In the meantime I've made arrangements with the attorneys of absa that I will repay them in three premiums that are due on the 15th of each month. After that arrangement they still went and ran debit order on the 1st of every month this year. I have suffered with bankcharges. Thee result of this is that I no longer deposit my money. As soon as money is available they run debitorders! Now I'm suffering cause there is never money in the account for the other debit orders and its costing R138 for every returned debit order.
