Bharti Airtel — internet services.

I had dome my airtel recharge of rs. 399 for 84 days in which i am getting unlimited calls, 2gb per day, 100 text messages per day. But the internet services that airtel is providing is very poor. I had my most of the work on internet only but due to the very minimal speed i cant get my work done on time.
As airtel is providing 2 gb data per day acc. To the above mentioned pack but i am unable to use whole data per day due to low speed.
In future i will never get this poor airtel connection. As comparatively jio is the best.
