Airtel — slow internet network

Address:

Jalgaon, Maharashtra, 425434

Issue about airtel network. It shows 4g on notification bar but actually it cant speed up any site as fast as expect. Airtel says fastest network ever by ookla but when i test it on speedtest app of ookla. Its say network problem. When i test jio its connect to speedtest and gives interet speed result but airtel cant connect. I use jio also its working better and fast. What should i do for about network and speed.
