Karvy — mutual fund investment without consent

Address:

121006

I had opened a demat account with karvy stock broking ltd...and given them a cheque of rs 10000 for crediting to my demat account.
However, upon asking for returning the same to my saving account from the demat account, the firm only returned 9000 rs and I was informed that my 1000 have been invested into hdfc mutual funds.

I have not consented to the said investment and nor submitted any form regarding the same.

My funds were misused and diverted from my account without my consent.

So the firm may better pay my money back alongwith the bank interest for the same amount from the date of the fraudulent investment executed without my permission
