It may be that the buyer is in complete compliance with the agreement and just not returning calls, for whatever reason. There is no way to know. You can not just terminate the contract, the buyer has rights as you have mentioned.
You might be able to create a back up contract with another buyer that is conditioned on the failure of the first contract.
