HDFC Bank — HDFC Bank - Undue deduction of Depository Charge

Address: Mumbai City, Maharashtra

I have a salary account in HDFC since April2012. I was offered a Demat Account as well and assured that it is completely free of charge and will be chargeable only i[censored]sed for trading. Now yesterday on 12th may 2014 there has been a deduction of 842.70 from my account mentioning "Depository charge for APR14 ". But I have never used or logged in with my demat account since 2012 when it was opened. Then how this undue deduction of money was done without any prior intimation. I was fully assured that the demat account doesn't have any charge and was hence coaxed into opening one. So, this sudden deduction is completely unacceptable. Look into the issue at the earliest and revert my money back to me as it is hard earned money.
