We crossed at Nogales and turned in our tip at km 21 midday on Monday. As of this morning no refund yet. In the past has shown up the next day as it is supposed to. Anyone else experience this?
Ours took one day - it is on a credit card and should be automatic. You should have gotten paperwork and cancellation validation etc. Could take a couple days but not more than that - if everything was entered properly - I stayed and watched the credit card number go in and everything.
