Cognizant — cts offer letter

I have attended interview on 9th June. Completed till hr round. He told me to release offer within 15 days. 6th July I got call from HR . unfortunately I didn't attend his call on that time. I called him after I saw the missed call. He told I called you for final discussion, I am out of table now I will give a call tomorrow .

But he didn't give a call, so I called him yesterday now he said ur profile waiting for approval I will get once it get approved like this. Now I get confused, one day he said called you for final discussion and other day he said waiting for approval . Whether I get offer or not??
