I won my chargeback dispute, Carrie, and have also written to the executive contacts at Homeaway since you provided them here. I shared with them my ordeal and the lack of guidance provided by the "chargeback specialists". I've also asked for travelers to have to create a personal account to be able to make a reservation. They need to have a username and password, so that they are self identifying. If that had been the process, this kind of thing would be much easier to defend.
