Same experience, first time in Miami, August 2018. I rented a car to go to the Everglades. I did not get the $50 per-week Sunpass that Thrifty sells. Not being familiar with the freeway system, I wanted to drive on the streets, but even though I would program the GPS on my phone "to avoid toll roads", it kept directing me to the toll roads. I got frustrated and tired of that so I tried to get a toll pass at a store but they didn't sell it. I called Thrifty to get the pass added on my rental agreement but they didn't. I was told I could pay for it when I turn in the car. When I told the man who received my car I had used the toll roads I was led to believe that the charge would be applied to the rental. Weeks later I received a bill for $79.92 of which $69.93 were for "administrative services". Two days later i received an updated bill with another toll date added bringing the total to $90.18 .
I...just called Thrifty and they reduced the charge to $52
