Loan repayment debacle with Standard bank.

I app**** for a Standard bank personal loan online, I submitted documents and got approved. One of the documents was my bank statement from the bank into which my salary gets deposited, and I thought the monthly repayment will be deducted automatically from my other bank. First month I waited for the loan debit order to go through but nothing happened. I received an email about my account having being handed over to collectors because I defaulted. The company name is Daly, some company in KZN. The company started debiting the loan repayment from my other bank monthly and at the same time Standard bank was also debiting my account for the very same payment. I went to the branch, submitted a proof of account from my other bank so that they (Standard bank) may start deducting the loan repayment from my other bank. That hasn't happened, I'm still paying via Daly and the debit order at Standard bank is still very much active, most of the time it bounced because of lack of funds and I'm being charged for that too. I'm sick of this bank and their nonsense. I instructed them to stop the collectors and deduct the repayment from my other bank, they gave me Daly's contacts and said I must be the one canceling that transaction. I wasn't the one who handed my account over to those people in the first place.
