Samco Securities — Account balance is less than the amount transferred in account plus the profit even after making profit

My client code is DS30210.
I am day trader and makes good profit in each trade.
Recently I switched my account to samco securities.
To get the practice, I used small amount.
I transferred Rs. 7500 in my samco securities in the month of November 2021.
When I checked the historical profit and loss statement for the period from 03 November 2021 to 09 December 2021 it showed profit of Rs. 646 after all the taxes and charges. The account balance would have Rs. 7500+646=8146.
But the fund available in my account is only Rs. 6314.
This seems to be fraud or something fishy.
Samco may be charging some hidden charges.
