After our lease ended, I requested for an invoice for the excess mileage charge and other fees. Their representative kept telling me that I need to wait until I receive. After few months later, I got a phone call from Hyundai that I missed a payment. I made calls after calls to make sure that they need to send another invoice via mail and/or fax. They kept saying that they already send one, but I didn't receive any from them. One of representative was really rude that it is not their fault that I am not receiving bills. I finally did managed to receive the bill via fax after making endless calls one department to another. The simple as receiving an invoice is this difficult, I really don't want to deal with them anymore.
