Airtel — airtel's so called "free incoming calls" is still deducting huge money on incoming calls from my account.

Address:	Hyderabad, Andhra Pradesh, 400016
Website:	airtel.in

Airtel has declared that all the incoming calls are free on their local or roaming network but they are still charging for the incoming calls. Why is such a telecom giant like airtel is lying to its customers. They have deducted 14rs. On my last call and more on previous calls. I want to get my amount refunded from airtel since they are traping people by a lie.
Ps: you are not helping your customers, you are forcing them to move to jio network.
