Cognizant — Offer not releasing

I have done with the HR round on JUNE 06, 2022 & also submitted the CIS form, HR has told me that she will be sending my profile to business team to get the package approval.

It's been more than 18 days still i didn't get the offer letter or any update from the HR about the offer letter, I have tried following up with HR but they didn't give response.
After 18 or 20 days they mailed me we have budget issue so we cannot go with your candidature.
