HDFC Bank — Unaccepted deduction of amount from my account

Address:

New Delhi, Delhi

I must say HDFC having very worst customer service and specially their executive. They are everything to tell you except your solution. Since 8 months amount of rs500 getting deducted from my account without any reason and intimation. When I call them they just give the complain number nothing else. I want my deducted amount to be credited to my account.
