Heart attack on vacation

So on the fourth morning of our vacation our friend had a heart attack, and a day long nightmare started for us and lasted a week for him and his wife before they finally got home. Good thing is the General Hospital stopped his heart attack, bad thing is we felt we were being held a gunpoint for money and lots of it. The director of the hospital is just a heartless little ????? you know I don't want say because I know it will piss someone off for sure. So to everyone out there this is a warning, you will need almost $25000.00 cash in pesos for emergency care and a trip by ambulance to Acapulco for more advanced treatment. The director of the hospital he doesn't care about your loved one, he just wants his money, no credit cards, no american cash, just cash pesos. Try doing that with withdrawal limits at ATMs and finding a bank to convert american money to pesos, not a easy task my friends, yes I do bring pesos with me, but I also have american cash too. So if anyone knows of a better way, or place where where we should ask to go to incase of an emergency please let us know. I have been coming to the area for 17 years, but this is the first time we have had an medical emergency. Thank you in advance for any medical suggestions.
