FNF, PF, Deferred Salary not cleared

Hi, I have worked for start up company for 1 year. From day one my manager for harassing me due to my salary almost similar to him. Being woman and I was software person still company asked me to work for vendor management, purchase order, admin,hardwarenetwork, project management etc. I was manager IT but was doing multiple department job. They put me in performance if I ask them that my manager is harassing me and not telling me the project details. Its not my mistake he hides the details of project. During sep 2020 they decreased my package verbally no consent signed by me. They are deducting the deferred salary since April 2020 and giving delayed salary for 1 to 2 months. Complete year I tolerated management and my manager. But in Nov 2020 I was asked to leave organization because now they are going to do Live.Complete year they used me in projects. Now I am doing followup for my FNF,deferred salary, PF not added to my epf account. Please suggest as I sent them email of final follow up and will send legal to them.
