My experience with CC companies and these kind of issues is that they always side with the consumer. They typically instantly remove the funds from the vendor's account and credit your account pending further responses from the vendor, which usually don't help their case.
You're probably in pretty good shape there. My hunch is that they will force the vendor to take the saw back and issue a refund.
