Franchise India Holdings — Franchiser not refunding my advance

I as a franchisee paid advance of Rs 10000 to franchiser What a sandwich for starting it's franchisee but after analysing I found it's not going to work in the approved area and requested them for a refund. They are now mentioning new policy which was never agreed upon that amount will not be refunded if reports of swiggy and Zomato comes positive.
Request the team to look into this urgently. Proofs can be presented upon request.
Thank you
