Cheating from Project Manager in Microsoft Bengaluru tell me whom to contact in Microsoft for solution

Dear friends

I worked with Microsoft, Bengaluru for 2 months, the Project Manager has cheated me by falsely rejecting my chronus time sheet. She has blindly rejected all the days I worked with the company. Now I may not get any money for the days I worked with Microsoft.

Tell me whom to contact for getting help under these circumstances.
