Company not paying the salary

Hello I worked with a software company totally false information right from the hiring. Position offered was Relationship Manager but were forced to be tele caller. CEO is least bothered to look what is happening in the company no training was provided for sales background. I had a family issue that my mother in law suffered from both the kidney failure so I took leaves (loss of pay) for 18 days in the month of March. However while interview I already set an expectation that this situation will come. At that time they assured me that they will help me. Moreover no body from my company came to see her at hospital. I have all the Skype chats proof where he said that he will come but did not come and was a totally false person. The biggest concern is now they are not paying me the salary for the 13 days I worked in the month of March. I want a compensation by more than 10 times and want to file a complaint. Moreover their main work is to fool the customer and make money and give worst services for the software taken. Can I file a complaint against that?
