Avis Vrbo Property

I had this rental booked for a month. I didn't hear from the property host about check in details, so I sent them a message the morning of our trip. I received a message a couple hours later that they were sorry they overlooked our reservation and the unit was no longer available, so they cancelled it. We were already on our way driving up to our vacation when we were told we no longer had a place to stay. Totally unacceptable.
