Airtel — no incoming calls - for my airtel number reg.

Address:

Erode, Tamil Nadu, 638401

I have recently ported my number from aircel to airtel. After 8 days, i am getting mobile data and outgoing facility but can't able to receive any incoming calls and sms which is very mandatory for getting otp for banking..

As i am an academician, i am supposed to get calls very often from my higher officials and students.

In this regard, i need urgent attention from the mobile service provider in solving this issue, help me out..
