The issue in GetHuman-joeboy's own words
When I was making the reservation for myself and Robert Vargas. Your site said that something had went wrong and the reservation it could not be completed. So I made the reservation through a different site. Now I get a message from you saying that the reservation is confirmed. So now I have two sets of reservations. Please cancel this reservation for Michael Kasten and Robert Vargas. I have Made reservations through another site.
