Trai — Low speed on 4G network

The telecom companies like Vodafone and Idea cellular charge the huge amount on recharge for 4G internet. But they are unable to provide the speed of internet which they claim in their advertisement. Most of the time their speed of internet is around 60-80 kbps only. Which is less than 2G speed. So they don't have right to charge the amount of 4G internet speed for 2G speed. I am from Goa. But I never get the good speed on Idea and Vodafone network.
Reliance Jio provides the service at good speed.
Trai is not doing anything to force the operators like idea and Vodafone to provide the services for which the customer pays.
