Rental pickup and drop offs went smoothly, but final billing has been a disaster!

Avis was good, EXCEPT, they made two unauthorized charges to our credit card with no explanation, or copy of a receipt that may help. We dropped car off early in the day, so no attendant. Avis was also aware of extended rental, as the desk attendant had to ask another attendant about what to do, and we assumed that this was allowed for, but it wasn’t reflected on our rental agreement. Very difficult to reach anyone at Avis to discuss this. Placed on hold for over an hour, so I just hung up. I will try again to reach them to discuss these issues.

I will be expecting a refund on this guarantee once I receive a receipt from Avis. They have not given us a receipt for the rental, to explain unauthorized charges to our card, that we do NOT know the reason behind.
