Received a fake experience letter from my last company

Hello, My name is Priyanka Gupta and I worked as Ecommerce Account Manager for more than the last 2 years(6th June 2018 - 24th July 2020) in my last company, named Unique Sellers & Co. HUF. After 24th July 2020, I needed to go on leave as I got infected by the coronavirus and had to completed my quarantine period. But meanwhile, my boss hired someone else at my place and did not even inform me about this. After my quarantine period was over, I phone called to my boss Mr. Gurmeet Singh Pooji on 28th August, 2020 and told him that my health condition is good now and he told me that he had already hired someone else at my place. I did not complain him about it but simply asked to provide me my Experience letter/ relieving letter, so that, I could join a new company with my 2 years of working experience. But My boss took about 15 days to provide me my experience letter and gave me a fake experience letter, he did not even mentioned my working period in the company,i.e, from 6th June 2018 - 24th July 2020, and my annual salary, i.e, ₹1,38,000. So, I need help in this matter. I want my experience letter with all correct details mentioned in it and not the one with altered information. Regards
