I have worked with first company in January 2013 to June 2013. Here I have offer letter, experience letter, salary certificate use to get by hand. When I joined in TCS BGC verification was done and I worked for one year. Now I got a job in WIPRO before joining they are doing BGC, here I should join on 18june 2018, it was postponing due to BGC FAIL now first company operations were closed and they were unable to respond from official mails what can I do?
