Capgemini — About Releasing the offer letter

Hello,
I am Maheshwari, I got selected to the Capgemini more than a month ago March mid week 2021, my package and everything was discussed and was waiting for offer letter to be released after a week asked me to submit complete bank statements I did it, waited for a week dint get any response from HR and I left all hope, suddenly after a month on April 25th 2021 got a text from HR asking what is your notice period, I replied him he said he will be releasing the offer letter, it has been 4 days again still my offer letter not released.I just wanted to confirm whether they are going to release my offer letter or no, or they just wanted to play with the emotions of candidates
