Online Share Trading By Broker Without Opening The Demat Account.

I have been involved in share trading with INDO Thai broker from the last 3 years. Earlier I was involved in trading of around 30-50k. Now my broker told due to the lower circuit all my money is lost also he is asking to pay 4 Lac rupees. So now I wanted to know how this much amount is being lost. First thing I came to know: 1. I don't have any separate Demat account broker who was doing the trading in his own trading account. 2. When I asked for the total transaction history so that I can crosscheck or verify all my share details went correct or some cheating is involved. 2.a. He provided the excel document sheet. How can this be a valid transaction proof? 2.b. I asked I need a valid online share transaction report. He told me I cannot provide as I am dealing with 200 clients in my own account so I will not be able to provide. 2.c Also I came to know he was adding the interest of 18 percent per month on the margin he provided on shares. I am in huge pain due to this. Please suggest me. I have all my online money transaction details which were credited into the broker account.
