Best transportation service in Omaha, Nebraska (NE) 2024

So is it normal practice to charge both the estimated total as well as the deposit to a customer's credit card once the rental is returned? Especially when the car is washed and vacuumed before returning it to the facility? Doesn't make sense due to the fact that the deposit/auth is supposed to include the estimated total and any additional charges/fees? P.S. - It's difficult to actually get them on the phone too. The line's are usually busy. Probably from answering all the questions concerning the extra charges. ~KTreSev
