HDFC Securities — Unknown charges taken by HDFC sec

Hi,
I became a customer of hdfc since 2015
I could find that Many time amount is debited from my account against Net pi to hsl sec a/c 2545405

Transaction :
Net pi to hsl sec a/c 2545405

I was charged so much money since opening this Demat account and i specially mentioned i don't require any demat account, i have contacted hdfc and i am not satisfied with the approach and further they said it is hdfc securities and demat charges which i informed i don't want and cancel and refund my money back.

Else I will go with legal complaint thru consumenr court also will inform to SEBI againt this additional hidden charges.
