Wipro — Delay In Onboarding from past 3 months

I got offer from Wipro on Jan 24th 2022 after that i had got green audit mail and addendum letter too mean while I had got my internship offer too from Wipro up to 3 months, I had successfully completed the internship too along with my 7th semester after that i had my joining date as 30th May 2022 but due to my 8th semester exams they offered me the postponement option and i got a call from them as they postpone the DOJ to July 4th but on that day also I didn't get any details or mails regarding my onboarding, i had completed my pjp too but still now there is no mails regarding my onboarding i am still waiting for that.
It was my dream to work with one of the greatest MNC like Wipro in India.
