FIR for denying employment and non payment of salary?

I am from indore(MP).in 2017-18 i was sent abroad(kenya) by my employer to work for their new company in kenya.duration between my first and last visit was total 18 months,in which i visited kenya 4 times and lived their around 11 months.for all my visit my employers provided me air tickets,accommodation and other living expenses were also provided by them.for this work an amount(salary) of $5000 per month was decided between us. due to some business problem they did not paid me any single salary at kenya, although they paid me a small amount (in parts) here in india from the same account as they were used to(indian co. account). whenever i asked for salary through emails, they replied they will settle it soon but they never paid.last month i sent them a legal notice asking for my dues and they replied that there is no relation of employer -employee establishes between us. now i am planning to file a FIR for "dhokadhadi,badniyati,vishvasghat,mental and financial harasement" by them. am i doing right,pls suggest.
