Removing someone on probation without reason on 3rd day

I have question regarding my first job as formulation chemist in a ISO certified chemical company 3 weeks back. I was hired after a interview in a chemical company, my documents were taken and told to join on next day, Accordingly I joined, * On first day I was told to read procedure of lab from file. * On second day I was called told to meet technical head to understand my job. *on third day I was told by HR that I'm incapable of handling lab all alone and I am very raw for this job. And told .HR said they will give me 10 days sallery for compensation. I understood my job completely and told Technical head accordingly still I was fired. Actually I was interviewed and selected by MD of company as it was small company overrulling technical head which I Understood by communication between MD and technical head. I'm pretty sure that I became target of technical head's ego. As I was not given any chance to prove my skills and holded my appointment letter back to fire me. I communicated to MD of company through Linked In but he said there is 7 days probation period, when I said I joined only 3 days back then be blocked me. My questions : 1. Can I file any complaint with Labour commissioner? (As I was not given any appointment letter)
