Well, in defense of uber, we have monopoly cash. As of today, they should have applied “dolar tarjeta”, the drive probably negotiated some overpriced “dolar blue”

In either case, I’m sorry for your trouble. Idk if it is still like this, but it should be better to grab an uber than a cab here. If the cab driver recognizes you as a tourist, he will do a detour just to add Kms to the bill.
