HDFC Bank — fake transaction

Address:

1/B-8 door no 6-27,Venkateshwara Co-op industrial Estate Balanagar, Hyderabad, Hyderabad, Telangana, 500037

Rs. 885 have been deducted and when i checked the mini statement it showed that it was a DCD Transaction. Today i.e. on 9th December when i came to know about this false transaction. Would request you guys to get the amount again credited in my account. It's really embarrassing to use HDFC Bank because i feel my money is not secure enough.
Kindly look into this case and get it resolved ASAP.
