We booked a car with rentalcars by Hertz with 4500 km included. We have driven 3415 km but we had to pay $140 extra because Hertz had an agreement with rentalcars only for 2520 km included. We contacted Rentalcars and they promised to look for a solution. After all the time, they still didn’t come with a sollution and respond no longer on my mails. Like the painting I bought from handmadepiece.com they double charge me and they said they will come back with me with a solution but they no longer respond on my call/text messages and email.
