Address:

Mumbai City, Maharashtra, 400080

Dear Sir/Mam, I am one of your account holder Mr. Mayank Mahesh Paua (sarvodaya branch mulund west), i would like to lodge a complaint against your branch, whereby they have deducted funds of Rs. 5700/- from my account without my knowledge. In case if they required money they could have asked for cheque from me. How they can deduct funds from my account without my knowledge?? Also, it will not take much time for me to go to consumer forum. Kindly revert at the earliest.
