Relieving and Experience Letter.

Hi. Ganesh from bangalore 4 years before i worked in Healthcare distributor company as sales Executive. Everything was going well untill my resignation. I was forced to leave the organisation without serving notice period due to personal reason. (Fathers health issue) But my company has raised false allegation against me about Misappropriated of Cash and office stocks etc..... Relieving is delayed and told me to serve notice period and solve the issues. I was in dilemma but Situation forced me to accept the order. But My Reporting manager has left the organisation after my resignation. Anyway i stayed in the company to solve the false accusation and prove myself so i extended my tenure till march 2018 to sort out the issue related to my office consignment stocks , Doctors samples and Payment issues. Again they denied by giving excuses . I left the organisation on April 2018 and Started working in my fathers Construction business .On October 2018 i got a mail stating same reason Misappropriated stocks are still pending and major shocking news they have added non related accounts and other employees teritory stocks missing into my Stock Statements and blackmailed by saying legal steps and Termination stories. But i do belief in my character and replied to their Email stating during my tenure as a senior sales Executive i have sorted out all related and non related issue beyond my limit now i cant bear more responsibilities . If your statement is true please proceed further investigation and Legal steps. I will face but later on i didt got any mail or calls related to my Email. After 3 years completion in our own project . We were forced to Stop the projects . Reasons 1.Incurred loss due to Covid Pandemic and finds difficult to continue business. 2.My father retired from his service due to health issue (58 years old) and interested to stay in my native Place. I left with two option either by continuing my fathers business or restarting my Career in healthcare industry. I choosen 2nd option and applied for job in few healthcare industry and got selected But due to pending relieving letter and experience Letter. My Employment is still pending . Even my Pf account is also blocked. After almost 4 years of gap. Last week again i sent a mail to my previous company seeking for my relieving and Experience Letter but they are denying my request and giving same excuses by saying irrelavant stories and by adding new stories. Note : After resignation on 2017 1) I extended my tenure without any salary for 4 months, incentives ,Bonuses and Allowances. 2)I have bank statements and few supportive documents. 3) Many Employees left the organisation due to covid and other reason including my General manager and HR. 4)Not bothered about of old dues and Salary 5)I need relieving letter and Experience . Can i file any lawsuit if they denies or any alternate solutions. Email : [deleted]
