ITC — Distributor cheated our organization.

I am a Retailer at Jaipur, Rajasthan. I am a big purchaser of ITC products from Jaipur distributor.
But he cheated us, he sent nearby expiry items to our store, and said if they got expired we will replace them. But from last 1 year he is not responding to our calls and messages. I visited his office and he clearly denied to replace my expiry.

What should i do now?
I will file a complaint now in Consumer Court, but before i request you to clear the matter outside it.

Thanks & Regards
