Reliance Money — Unauthorized Transaction to my Account

Dear Sir/madam
I am having and Demat / trading account with reliance Money.
Following is the account details:

A/c Holder’s Name : Snehal Harkawat
Client Id : S00041624
User Id : SNHA0001

I have bought an TCS July Future on 10/07/2008 which has been sold by RMoney back Office without any intimation to me.

If there is any shortage of margin, I would have transferred it on same time if I have been intimated. Even margin can not be the reason as 17, 303 INR is still there in my ledger balance and i have Stocks of worth Rs 1, 00, 000 around..

I had to carry of Rs 33, 000 loss as a result which is not acceptable.
Even the order has been squared off at 12:20 pm which is not the market closing time.
Settlement must be done on closing basis.
please let me suggest what can be done to take leagle actions againts them.
