Developer - Avis employé Programmer RV Technologies

I just worked for 6 months there and I am happy that I left the company. I had to leave under some circumstances, so I requested them for that but they clearly disagreed and said no. But I left anyways without my salary and experience letter. Today I am working in a well renowned mnc and I am happy that I took the decision to leave the place where employees are treated like dogs and have no existence of themselves . Worst company, with very long working hours..
