Airtel — 4G Network connection is extremely poor

I am residing in a place called Monnavedu village - 602021, Tiruvallur, Tamil Nadu. The Airtel 4G network connection over here is extremely poor, it is working under 1 KBps. Since all the companies are asked to let their employees work from home, I am totally dependent on the internet for my work. I have contacted almost every fiber network providers including airtel, since its a remote village, people told me their services are not available to my area. So I bought Airtel my wifi dongle, but still i'm getting extremely poor network connection(under 10 KBps while using Airtel wifi). I kindly request you to look into this issue immediately and please do the needful.
