SUNDARAM BNP PARIBAS HOME FINANCE LTD Proceessing Fees Charged with Loan being processed

This is with reference to my home loan application ref no# 1035899673 which was been approved but not processed because I need to submit additional documents for processing. I had given a standing instruction to the bank that you need to wait for sometime as it will take some more time to submit my documents because of personal reasons. Without processing my loan and completing my complete documentation, Sundaram deposited my cheque "912042" amount of INR 2950 for clearance and the amount got deducted from my account today.
I wish to know as how can the bank deduct the processing fee without processing my loan in advance as this is against the norm of RBI as per my knowledge goes. I want someone from the bank to address this issue immediately or else I need to escalate this to the higher authorities. Need a quick resolution on this concern.
