Bharti Airtel Ltd. — network quality

Hello i am dharmeshwar chaudang i am from assam. I am a very old customer of airtel. Our whole family is in airtel. But from few days i am suffering in poor network quality in my area. And i don't get 4g coverage in my area. While jio is giving 4g coverage fully in our area. But, what are you doing? So i am using a jio sim now for internet browsing. And i even can't make a call without any problem. What can i do if you don't give me network. So i request you to please provide a good network in my area. I had complained you much about the problem. If you don't provide me a good network i have to port my sim to vodafone. My address is - nachani no 1, p. O.- nachani, district - dibrugarh (Assam).
