Airtel — I am complaining about the problem faced in linking my aadhar with airtel number

Address:

Tirunelveli, Tamil Nadu

Sir
I have visited Airtel service centre in Onnarpettai Balaji communications and they have told me to link my aadhar by giving 14546 number. I have explained him that I am from Andhra and my sim is taken in Tamilnadu them he is asking me to travel Andhra for linking aadhar to my mobile. Is there any other possibility for linking aadhar??
