Genpact — Genpact fake job offer letter

I received a call from Genpact stating that my profile has been considered for a role in IT dept. 1st round was taken on call verbally, 2nd round was technical round, they provided me with a link to give the test but I couldn’t pass that test as I didn’t have technical knowledge, but after couple of days I received all from that person stating that they would still consider my profile and proceeded with 3rd round which was with Operational Manager. Once this was done after 2 days they sent me an feedback email stating that they would require universal identification number from IBM Cognos Analytics. They have given me 15 days of time to get certified on that particular tool by sending me an INTENT OFFER LETTER and provided me with a link to enquire about the course. I enquired and the person called me and gave me an overview and details of the course and asked me to pay the fee for that particular course which was around 15, 400 rupees. I blindly agreed for it without even researching for that particular course on google. Because some person who called herself as HR Manager told me that they would reimburse that fee in my first salary. I paid for the course and started taking classes but that HR from Genpact stopped responding to my emails and calls. I suspected that this person could be a fraud and I checked with couple of people from Genpact whom I know and gave them the email addresses of those HR’s and also asked them to check the INTENT OFFER LETTER which they had sent across. Then it turned out to be a fake letter and those people are not at all part of Genpact. Email ID’s of those people ended with domain (genpactinc.com) which is not part of Genpact Organization. Please be careful of such frauds. After realising when I searched on google there is no such UNIVERSAL IDENTIFICATION NUMBER given in IBM Cognos analytics.
