My firm had taken a franchisee of a company headquartered in Bangalore. After making them the payment of full franchisee fees of Rs 5 Lacs (inclusive of 2.5 lacs as refundable business deposit) via cheque, the company didnot perform and failed to provide us with the services offered by them. We dont even have a written agreement with them. We then left the franchisee, and asked them for the total amount back. The company said that it would refund only Rs 2.5 Lacs which was paid as business secuirty deposit. Can I claim full refund from the company via law ? What legal steps can I take against the company for refund of full amount ?
