Cognizant — offer letter - not released

Address: Ernakulam, Kerala

I got selected for the post of informatica developer for the interview held on 17/11/2018 in muthoot technopolis cochin. I have cleared 2 technical round and one hr round in which my package was finalized. On nov 23rd i received a mail from cognizant tag team stating my application has been kept 'on hold'. Can you please let me know the status of my application. Hr informed that i will be receiving the offer letter within 2 weeks after the interview and it’s been nearly 3 months and there is no contact from your side. I didn't get any reply for the previous mails. This is the second time i am getting selected but not receiving the offer letter from cts (May 19th/2018 also i got selected, but not received any offer letter). Can i expect offer letter?
