Actually, I am in trouble. I stopped working at my previous company since my salary was due for 3 months. However, the mistake I made was that I didn't send them any formal resignation letter. So, they took advantage and sent me a termination letter intentionally. At that time, I didn't bother much since I had already secured a job in my current company. But now, when I am attending interviews, they are asking for the release letter, experience certificate, or payslip from my previous company, which I don't have. I tried to contact my previous company, but now they are charging INR 50,000 for these documents. What can I do now?
