The last time I used Enterprise, about a month later a mysterious charge for something about $250 (I don't remember the exact amount) appeared from Enterprise on my bill about a month later. The Enterprise rep on the phone was not familiar with the charge code and had to look it up. It was for -- I kid you not -- windshield washer fluid. I did not use the washer -- even the wiper -- duing the time I had the car. $250 is a lot for wiper fluid. Either that thing has a 100 gallon wiper fluid tank or they're filling their wiper fluid dispensers with Château Lafite. The woman on the phone was also shocked by such a huge charge for such a silly thing. She had never even see anyone charged for windshield washer fluid and wasn't even aware there was a code for charging for it. "Oh, I'm sure it's just a mistake," I said, "and I'm sure you'll reverse that charge immediately. Yes?"
"NO! I am not authorized to reverse any charge. You will have to talk to someone at the office you rented through to get the charge reversed."
So, I called and spoke to one of the customer service people in the local office. He was equally surprised by the charge. But, he also refused to reverse it and referred me to another person who was not in the office at the time.
When I finally got ahold of her, she was equally stumped by the charge by also refused to reverse it saying that I would have to talk to the office manager... who was not in the office at the time.
When I finally got ahold of the office manager, he was equally stumped by the charge but also refused to reverse it saying that he would have to "investigate" it. "Investigate?" Investigate a $250+ charge for windshield washer fluid? What is there to investigate? Windshield washer fluid is like a couple of bucks a gallon retail at the local auto parts store. Even Mercedes-Benz only charges like $10 to fill the windshield washer fluid... and you get coffee and a pastry while you wait. But, no, he refused to reverse the charge without investigating.
So, I called my bank. They e-mailed me a Visa dispute form. I filled it out and e-mailed it back. They said it could take Visa up to 90 days to investigate. A couple of days later, I got e-mail from Visa saying that it was obvious to them that this charge was bogus and unauthorized. Visa reversed it. Visa charged Enterprise something like 15% (I don't remember the amount) for a "reversal" fee. Visa penalized Enterprize something like $35 (again, I don't remember the exact amount) for an unauthorized charge. And Visa put a black mark on Enterprise's merchant account (the more of these a merchant has, the higher the rate he pays).
A week or so later, the local Enterprise manager called me up saying, "I'd like to ask you a few questions about this char...."
"No need! If you will check your merchant account, you will find that Visa reversed the charge, penalized you, and charged you a fine! I'm happy. Good Bye."
So, I suggest NOT using Enterprise.
