Airtel — rent not paid as promised in agreement for sharing vodafone

Address:

Shimla, Himachal Pradesh

We signed an agreement on 29 june 2015 for sharing vodafone network from airtel tower installed on our land. This is clearly mentioned on agreement that airtel will pay us inr 1500 per month as rent. But they are paying us inr 1200 per month. This is clearly an act of fraud.. As airtel has breached the agreement, now i want the balance amount to be credited in my bank account with interest.
