Samco Securities — showing loss despite making profit and subsequently reducing the fund

My name is abhijeet srivastava. My client code is da33880. I am a very active trader on their platform. I am doing good in my trades however despite making the profit i have observed that my fund availability in my account is not as per the ration i made the profit.
I am highlighting the incident of dated 30-apr-2019. I had 29 lots of crude oil mini for june - bought at price of 4517, 10 qty, 4516, 10 qty, 4394, 5 qty and 4420, 4qty as per my calculation the average price is approx 4482 i sold all this at an average price of 4488 however the company showed it as a loss of rs 7500. On that day i made around 8000 rs profit in crude oil mini for june series but compacny shown it as 7500 loss and subsequently reduced my margin.

Same way for zinc i did shot sale of zinc mini above 200.5 rs but they shown it at avg price of 199.69 and despite making the profit on this trade they have shown it as a loss of rs 350.
I am highlighting these concern with them since last 2 months and no resolution provided by them. Request you to please look into this and help me connect with the authorities to escalate this matter and cheating about this broker.
