Airtel — airtel no. porting from corporate to individual after change of job.

I was working at gates india pvt ltd at punjab & my corporate mobile no. From airtel was [protected]. After i left the job & shifted to new location at madurai, i wanted to port the no from corporate to my name & also from punjab circle to madurai circle. My previous employer has provided the noc on airtel prescribed format. Twice i applied to a local airtel outlet at madurai, but funny excuses are given to me. 3 times person from company verified my new home address even. I want to know why my no. Is not getting ported? 3 times i interacted with customer care but got only assurances.
See attached the porting application & screen shot from the local outlet where i made application.
