I worked at Company 1 (a startup) for two years. Then, I joined an MNC, Company 2. Now, I have received an offer from Company 3. A few days after my last working day at Company 2, HR from Company 3 called me and stated that my BGV had failed because I allegedly lied. Surprisingly, the BGV vendor received an email from Company 1 claiming that I didn't resign but was fired for poor performance. Additionally, they stated that the documents I shared, the experience certificate and the appointment letter, were not genuine but forged. I do not have proof of the experience certificate, but I received the appointment letter from Company 1's official email.
Exactly one month before submitting my resignation from Company 1, I received an award from the company for my performance (medal and cash prize). My BGV was cleared by Company 2, which is also an MNC and is very strict with BGV. I informed HR that I could provide an affidavit stating that I did not forge documents and that the same documents were shared with Company 2 as well. Company 1 is lying and trying to destroy my career, or they already have. Company 3 is asking for an official email stating my date of joining, date of exit, and nature of exit (resigned voluntarily) from Company 1. However, Company 1 is not responding. What can I do?
