Notice Period Buyback/settlement Issue

Dear all,
I need help to solve my dispute with my MNC Company on resignation
I had to serve 3 months notice period and I served 2 months with 1 month buyback option.My company\'s Exit policy has a clause that allows 1 month settlement against accrued leaves.However my company is forcing me to pay one month gross salary and avail reimbursement on my leaves.
I will be loosing out on my settlement amount if I pay 1 month gross salary and get reimbursed for the leaves as the leaves are calculated for basic pay component alone.
Please suggest me how do I take this up with my company.I sent my HRBP a copy of the Exit policy and they are not responding to the same.

Dear Murali,
Ask your company for full & final settlement policy. If they are not abiding by it (policy), you can request them, still not complying you can go to grievance redressal machinery or OMBUDS MAN for the same in your company. Atlas, go to labour court.

Dear Murali,
Where are you based at present? In your details it is showing up as St Louis. In the states of the US, the notice period policy is different. Many states in the US follows "At will employment". Please clarify.
