Airtel — Sim card still not activated

I had lost my sim and that's why i deactivated my number couple of days ago.

Yesterday i went to airtel store and i requested them to give me duplicate sim so that i can use same number.

They assured me that the sim will start working within 4 hours. More than 24 hours gone and still my sim is not activated.

The number of sim is - [protected]

This number is not activated yet, there is no tower signal showing in my phone.

There is also no customer support on 121 and 198 number. We are unable to talk with any executive and also not getting solution on email

This is really very harsh experience
