Unreliable Cars, Over Charges, NO CUSTOMER RELATIONS

Cheap rate, possibly the cheapest. YOU GET WHAT YOU PAY FOR. Fox in Oakland Airport. For starters, business trip rental period for 3 weeks, Oct 24 to Nov. 14, 2012.  Within a few days, "check engine light" goes on. Had to skip a meeting to drive all the way back to Oakland and get another car, which was a roundtrip of 95 miles from where I was staying. Then Second's car windshield washer motor not working. I found out the hard way the next morning on my way to a meeting to Fort Bragg and I was driving in a fog, couldn't see. Too far away from Oakland to get a third car and did not want to miss another meeting.  Had to stop several times to throw water on the windshield so I can see on the twisting highway 128. A SAFETY ISSUE AND IT WAS SCARY DRIVING.  Fox sent a third car to meet me at Fort Bragg, I thought was nice but billed me extra charges of almost $100.00 . Since I used a debit, they basically kept my deposit.  Tried calling corporate customer service to get the charges reversed. What a joke that was. NO ONE THERE TO TAKE THOSE CALLS. You don't have choices to select to speak with anyone handling customer relations issues.  So I called Fox Oakland Airport and tried to talk to the manager I think name is Mr. Nguyen. He would not come to the phone. Steve answered and he said he was the "Lead person".  He needed to talk to somebody else, he said a manager but not Mr. Nguyen, and assured me he will call me back same day with their decision. One week later and NO ONE FROM FOX has yet to address my concerns.  I probably spoke with at least 5 different individuals to have my concerns addressed but all I got was the run around.  I rated one star but in reality, they deserve negative 5 stars.  By the way, all three cars I end up driving in that 3 week period had over 45,000 miles in the odometer. One had over 50,000 miles.  All had dings and scratches all around the body.  It's painfully obvious that routine maintenance and any form of customer service are the lowest in priority for this company.
