Karvy — investment made through karvy in hdfc mutual fund - pan aadpv1672l

Address:

Karvy Stock Brokers, Hyderabad/Bangalore

I had invested an amount of rs.50, 000 through karvy bangalore (Vivek was the manager) in hdfc mutual fund in 2017. I did not check the balances regularly as it was supposed to be in demat form. The units are not there in my demat account with kotak securities. I understand from hdfc mutual fund that the amount was completely redeemed in november 2018 without my knowledge. My pan is aadpv1672l. Please let me know the status of my investment and where the units are lying. How the amount was withdrawn without my knowledge and not credited to my bank account or demat account.
