I think the problems with ATM's in DR are extremeliy exaggerated. I have now been here for 9 years, the last 5 more or less full time. I use the ATM's as my only source to get cash, and for the first time, this tuesday i noticed that that my account had been debited double for the amount of 40.000 pesos.
I'm pretty relaxed, and gave it a rest for some days withouth doing anything, and today my account was credited for the same amount.
