Full and final not released

Dear sir, I have been working in pharma segment n I have a terrible experience to share almost 5–6 companies have not settle my genuine dues of salaries and expenses. Some are almost 5–8 yrs old n the latest one is almost 75 days old. Some have some special statements written on there appointment letters, which gives them freedom , and others seem to have no concerns at all. I cannot take legal action against them as a don't have so much money. In the latest episode, my company says that they cannot give me my full n final till the time stockist does not pays his dues to the company. In this regards, I want to inform you that 1 I have no dues on the stockist 2 I have returned all my property 3 companies settlement time is of 45 days 4 after fighting so long I have received one part as salary but expenses are still held they say that they will only settle my dues when the stockist pays his pending payments. 1 I have no dues certificate from all stockists 2 And my views on this is 1 I'm not in organization now, how am I responsibile for the old payments of my time, because it's responsibility of the current staff to follow up for his secondary n payments 2 party's due on company is around rs 46000 but stockist already has non sellable goods of rs 70000 in his shelf . 3 the current staff do not meet the stockist, help in liquidation of stocks or clearing payments. Kindly help me with your detailed view in how to get my ffs from this organization as I have 1 written several times on main with no proper response. 2 I have called many times to hr n concerned managers but they repeat same thing, ie payments of one stockist Kindly help me with solution to get my ffs from this n old pharma companies.
