Unpaid salary

Dear Sir, I had worked with my earlier company and got relieved after completing all my formalities on 01/11/2017 I've collected the documents signed from them on 24/02/2018 The proprietrix informed me that the final settlement will be done withing some time period as the financial situation is little critical. I accepted that and after few days asked as reminder over call, in initial days they're reasoning till one year. After that they're denying to pay me the final settlement of 17,000/- rs saying that she will lodge a complaint on me regarding I made loss in her business. Instead I helped them to get 1 crore rupees project even after get relieved. Along with that they are not paying employees what they are mentioning in CA reports as it's a cash through payment. (Example: if they are paying me 10k, mentions like 15 k salary, and other allowances 2500 rs.) This I came to know by glancing the CA documents when filing tax. We can say it a Daylight robbery. I do have few call recordings informing they will pay after few days. I just needed to know is there any ways to teach lesson for these people that not to happen/repeat same with any other employees. Please tell me whether I can lodge a complaint now or it's been too late to lodge?? Thanks and regards Vishwa
