They refuse to reimburse the rental car expenses. They said, they never ever received the paperwork. They said I have to fax it to them, but I have to find the fax number on the contract agreement .. NO fax number on the contract agreement . Then they said, maybe I sent it to a wrong P.O BOX number. I told the P.O. Box number what is on the contract agreement, then they said, it's not the right one. This company is a joke.
