Wipro — Delayed joining date

I got my offer letter in February for wipro wilp and the joining date clashed with my semester 6 examination so the HR member told to postpone the joining in a live event so i postponed my joining date but now it's been more than 4 months that i have been waiting for my new joining date, i have completed my bachelor's and got the final semester marksheet too but now I have nowhere to go.
