Cognizant — haven't received offer letter

Address: Bangalore, Karnataka, 560095

I attended an interview at cts bengaluru on aug 04th 2018 and cleared all the rounds. At the end hr informed me that i will receive my offer letter in a week but i haven't received yet. Meanwhile i received an email from cts talent acquisition profile under review. After that, i haven't received any updates. I am not sure if normally they would take almost a month to release the offer letter.
