Wow. Yeah, you'd never see anything like that here! My daughter was hit by a car and we had to pay all the bills. I swear we will wait around for at least a year to see our money, maybe longer. We pay so much for insurance and sometimes don't even use it but when we need something, its a long, drawn out process.
It's good that you are in Spain where you can get good healthcare and not be out of pocket so much money! Sorry about your knee.
