We rented a property through Sullivan properties but have had financial setback and want to cancel our reservation since it is a pretty expensive rental. I never signed the agreement they faxed me but the deposit did go through on our credit card. They have a no refund policy but can they hold me to it if I never signed the rental agreement and sent it back to them? They told me to take our trip insurance but that only covers cancellations due to illness or death. We canprobably still go to Maui if I find someplace less expensive to stay.
