Airtel — very slow 4g internet speed in area

Address:

Satna Cement Works, 485005

Current location is birla colony, satna, mp.
I'm not able to use 4g net here. It shows 4g is active but it's giving speed of 10-20 kbps inside home. I'm really pissed off.
When outside speed goes maximum 50 kbps. I have take hotspot from my brother who is using jio network which is far better now than airtel.
I've tried to restart my phone and done everything but no improvement.
