Claiming benefits upon termination after travelling to home country for medication

Madam,

I worked for a company in Dubai for 23 years and have not been paid my end of service benefits and sales commission.

I came to India for treatment and I could not resume my duty soon since the treatment was lengthy, so the company has canceled my visa and hired someone in my place.

I have requested severely to pay the service benefits but the HR manager misbehaved and threatened in an unethical and unprofessional manner! what should I do?

I can file a case against the company for claiming my benefits? I am paralyzed and can not walk properly now and suffering a lot! Can you please help me?
