Atos — recruiter giving fake offer letter

Address:

RMZ Centennial, ITPL Main Rd, B Block, EPIP Zone, Whitefield, Bengaluru, Karnataka 560048, 560048

I got a call for recruiter opening i attended the interview and recruiter told that i was been selected, after few days i see some other vendor releasing offer letter for atos which i was not aware and when i went to company for joining they told its a invalid offer letter. I quit my previous job for this opportunity and currently i'm jobless because of the fake promise what the recruiter gave me.
I want a justification, i have all proofs mails, chats of that concern person.
It is played with my career please take an action on this issue.
