Yes Bank — Cancellation of personal loan and take back the disbursed amount

Address:	411033
Website:	yes bank pune

Without any intimation personal loan amount is disburse into my account by yes bank, which is less than my requirement and now they are saying that You have signed the agreement and that is the proof that you were informed and agreed to all the terms and communication. also had taken blank cheque from me without putting any amount in the name of yes bank which will create any problem in future if they use in wrong way.
So please help me to sort out this problem by cancelling my personal loan and taking back the disburse amount without any interest.
