Airtel — I'm complaining about having no network at all

Address:

Sonitpur, Assam, 784028

I have complained two times already here. But airtel is making no effort in solving my issue. From the last 10 days i have no network in my sim card and i am facing a ton of difficulties due to it. I cannot make call to anyone nor that i can receive any call due to no network. Its just that i am studying in a university and i am using its campus wifi. I have not contact my parents from the last 10 days. Kindly look into this matter i am frustrated by now.
