Unicon Securities P Ltd — unauthorised trading

on being persistently requested i invested rupees five lakhs in unicon securties P ltd.t nagar,chnnai branch.
while i ws promised a return of around 15/20% permonth,I felt at least a return of 5% per month would be made by this company as my investement was purely for trading and the positive or negative movment o the market could not affect me.

To my shock and horror,this uniconsecurities t nagar,chennai branch, lost 3.8- lakhs of the my investement of 5 lakhs within about 30 trading days from the date of my investement.and till date no responsible person is willing to answer my question apart from a sales executive who is lower down the company.

i have entrusted the relevent papaers and evidence to my lawyer for filing a complaint with SEBI.
I would like to know if any one else has been cheated like this.
