Religare Securities — sold my shares even though I first deposited money and then traded

Address:

Bangalore, Karnataka

I have Religare account for 10 years, till now I had no problem, even though they operate very traditionally. I wanted to buy shares of NIIT Tech so I transferred 4000 in two transactions online, then called to buy 15 shares of NIIT Tech But branch guys did not punched on time so Religare sold my shares of different companies instead of NIIT Tech. The company shared of Hexaware, Aravind etc..which I am holding when they are below 50 rs. now they are more than 100 rs. My arguement is they should not have sold different companies shares, if they have sold the NIIT Tech shares which I brought recently after money is transferred. Any solution how to get my compensation?
