Airtel — tower or signal strength

Address:

517507

My name is arkadeep marik. I have 4g lte handset and activated 4g internet pack. But my handset signal shows maximum time h, h+ even e with 2 or 3 sticks. It rarely shows 4g signal with no sticks. I had contacted customer care theysaid me to check my mobile settings, clean the sim card and many other things. None of that helped me. I also tested the sim card on other devices which shows the same signal problem. I checked in open network that my locality have have good internet signal with 4g even there is a tower 1.5 km away from my locality. I had no other option but complain about the signal strength. My address is iiser tirupati, karkambadi road, tirupati, andhra pradesh, 517507. I'm using lenovo a7000 handset. Please look after the signal strength. I switched from other isp believing that airtel is best in internet services, but such experience is unacceptable.
