Debited for closed accounts

It makes no sense to me why Getbucks would debit my account when I have settled all my active accounts with them. I sent the proof of payment on the 19/08 & called them as well and was advised that the payment will be allocated. On Monday I chatted to a Kim Oane who assured me that the money will be allocated and my account will not be debited. Come today, my account has been debited for 3 accounts, 2 of which have been closed and one has a balance of R602.15. Why did you not debit the R602.15 only? It beats me. I called in and was told that my money will be debited at the end of the day. So you are quick to take our money and take your sweet time giving it back. I want my money deposited into my account immediately. How do you think I will pay for the rest of the debits that need to go off my account?
