As per your statement you have submitted resignation 3 times and revoked subsequently. Have you confirmed the same with your employer every time?. Have they collected any resignation letter cancellation note from you ? Have your employee ID/Number /PF number got revised every time when you revoked your resignation.
There are possibilities your Employer might have manipulated your service data with a break. However if you are sure of your continuous service without any break legally you are eligible for Gratuity.
As per the Act requirement send your employer a request letter (FORM I )mentioning the period of service (DOJ and DOR and total years of service) in case of no response or refusal from your employer you can file a complaint under Section 8 of the Act with the Controlling Authority ( Assistant Labour Commissioner) of your jurisdiction

I have just checked all my salary slips having the same joining date and employee ID, which are assigned to me initially.Company doesn't provide any PF , so there is no PF number. So seems I am eligible for gratuity. Thanks for replying.
