Driver forced us to beg for money

We took an early morning Uber in Mexico City, and I confirmed on Ubers website beforehand that tolls will be added to our final bill. But when we arrived at a cash only toll station, the driver demanded we pay the tolls in cash, and we had none at all. Since we also couldn’t do a U-turn, we had to get out of the car and beg drivers passing by for cash to pay the toll.

Does anyone know how I can report this, get a full refund for a ride, and stop the driver from rating me poorly because I had no cash? Uber customer support seems all but nonexistent, and their pre-written complaint categories clearly don’t include this specific scenario. I’m considering reporting this as “serious incident with the driver” and elaborating on the drivers behavior, but idk if that’s the best move here.
