Wipro — Onboarding Issue of wipro

Address:

Bangalore

In the month of May2022 I wrote my assessment and got selected for next round and i cleared everything for which I had recieved a acceptance offer letter. I was then pursuing my final year BCOM but recently only i completed my 6th semester exams . Now when i mailed my global manager He says that I am not being part of the team as i m not selected. Also says that i can do my part on complaining this on forums .
I need either a compensation or a job for this type of behavior from wipro . Manager says that there is no vacancy as of now to hire me . But then why did they select me earlier??
