i cancelled my permit at the kiosko then drove over to the building on the incoming side, cancelled my fmm then gave the car cancellation to the lady at banjercito, explained the situation in spanish, she gave me the form to fill out with old and new card info, i signed it left, 2 days later i get my money back. this is the second time ive had to do it because my CC got hacked and usaa cancelled it. no problem.
i also arrived at the colombia bridge a couple of years ago and couldnt find my tip paperwork, told the guy in the kiosko, he filled out a form and got it cancelled. told him it was stolen. no problem. got my refund in 2 days.
