Airtel — no 4g network. data speed is worst

Address:

Tumkur, Karnataka, 572102

My airtel network sucks every time. They call it India's fastest 4g network but it is the worst network i have used.data speed doesn't go above 50kb/sec. Worst experience. The customer service say it is because of congestion. How are u leading the company if you can't solve your network problems. From day 1 of my unlimited pack i have not been able to completely use my data pack. What kind of data service is this and u call it India's fastest 4g network. My city is a smart city and here u can't satisfy customer services means ur company is not fit for calling fastest 4g network.
