Demat Account — Dp charges without knowing

Hello there,
The bank has deducted dpcharges without any sms or without giving intimation to me. I haven't sold any mutual fund nor do I have any share in my account. But rs. 826 has been deducted from my account. Secondly dcard fees of rs. 924 has also been deducted from my account. The bank never told me while issuing me the debit card that they will charge me the same amount every year. It's really sad and unfortunate to know that icici Bank just loots the money of their CUSTOMER unknowingly. Please refund my money bank and cancel my dcard if you are going to charge this amount every year. Also please refund my dp charges. The bank never told me that they will charge this kind of charges. I don't even know what that is. Atleast the bank should call the CUSTOMER or send an sms intimating the CUSTOMER why they are taking our money...it's really ###. Please return both money of mine back to me asap
