We were renting a car and decided to purchase it since the car runs good, a used car for 5K plus.
I made several calls because of questions we had, the persons I talked to sounded like they were nor very happy I was calling, I guess they thought we were not going to make the purchase and they were waiting their time with me...
I called the girls/lady at the office to pay with a card, the transaction was made with no problem. I was waiting for a thank you for your purchase, or thank you have a good day.
Nothing was said!
So I asked, is this all? she said yes, I waited again for a thank you, NOTHING, so I then hung up.
Sure it was a used car, but it still was l a 5k transaction.
The 4 stars is because the car is good, but they need to work on customer service.
