Airtel — prepaid aadhar update

Address: 600079

Hi,
Basically i am from andhra pradesh who is having addhar adress as ap where i have my own house. As part of my job, i am residing in chennai and i took a airtel sim card.

As per operator direction to link my mobile number with aadhar, i visited chennai airtel outlet got the response saying that i need to visit ap airtel outlet.

Last saturday i visited ap airtel outlet, i got the response saying that i need to go tn circle.

Its been frustrating and please provide the proper steps.
