I doubt it too, but in highly regulated places (like Spain is, sadly for many affairs, luckily for some others) you could just pick the taxi number (they are always shown outside, license plate would work too) and complain against the city/company. Losing their mean of living is a pretty scary thing. As a matter of fact, I've taken 2 taxis in the UK and was scammed in one of the trips (first one actually), the second one was nice. Shit happens, everywhere.
