Airtel — plan services are not provided as plan description

Address:	Ghaziabad, Uttar Pradesh
Website:	www.airtel.in/recharge-online

Airtel is not providing the services as per description of the plan.
I was going to recharge of rs. 509 and the recharge description is
"unlimited all local, std and roaming outgoing calls, 100 sms/day and 1gb 3g/4g data/day. For non commercial use only."
(Reference: https://www.airtel.in/recharge-online)

And no t&c is mentioned there.

But their executives on airtel store are saying there are so many capping in this recharge like
1. User will get internet like 500mb in day + 500mb in night
2. User will get only 200 mins daily for calling (Not unlimited)

I am not able to understand why airtel is not mentioning what they are actually providing.
It looks like openly cheating with the customer.
