Hi, I am currently working as a Software Developer in a very reputed company. It has been 4 months since I joined. Suddenly, yesterday, HR contacted me to inform me that my Background Verification failed because of my previous company. Previously, I was working in a big company on the payroll of a consultancy. Now, the problem is that the consultancy is blacklisted, and that's why the BV has failed. I have been given 5 days to prove that I was really working in that company. I have lost faith in the current company, as in these 4 months, they could not reach out to that company even if the consultancy was blacklisted. What should I do?
