Cognizant — delay in offer release.

Hi team,
Attended interview on dec, 2018 for sql, ssis and ssrs and its been 9 months to release the offer. Done with all the process but no proper responds from the hr team. They it is in process and sometimes they say we don't have openings in chennai for now. I wonder about their answer. Hope your team will solve this and help me in releasing the offer letter.
