We've had similar issues with multiple agencies. Even the ones you can open/close on the windshield. We had their closed. I had added the plate to my own sunpass and some of the tolls went to their while others went to mine and I had to pay their ridiculous daily fees. When I did pick up the Visitor toll pass and this happened they actually refunded the rental company charges and it was easier than battling with my own sunpass. But with Jetblue in terminal C i am not schlepping to Terminal A for the pass. We've been charged by
Budget, Dollar, and
Avis so far. I can't recall which agencies we haven't had an issue with since I have no email trail from those experiences
I may just aim for the cash tolls like old times at this point. For us the only tolls we encounter are from MCO to AKL. Once we are onsite we don't head anyplace with tolls until heading back to MCO
