Dear sir/ma'am

From my point of view this is not right, i have left my previous job 1 month ago. Belhaf of iam joining genpact
And i was giving the interview from a month ago.
I was very disappointed, iam rejected it's no matter but matter is that after all process done then i was rejected without giving any reason, and from 1 month i didn't join any where because there is hope joining in genpact (One of the most reputed company).
So i want to say there is loss of my 1 month salary, this should be full fill, and i get new job even in another company by genpact
Also find the attachment for my offer latter provided by the company

Please take need full action as soon as possible

Thanks & regards
