Real Estate / Resigning from a rent that is not rightfully made [3]

I signed a contract with me saying that I need to get a lease starting from November 1. I said that I need this contract from that date and he didn't even insisted on that and started the date from this month that I signed the contract. Because of these reasons and being not rightfully made contract that is not made within my rights and requests. What can I do with it and what I should say that is within my rights? As I know from the starting date it's my right to resign from the contract within 15 days.
