Which part of R.U.S.A's were you enquiring about - the money exchange or investing section?
I have known Don Pablo for about 5 years & Apoloinar himself for a lot longer. I have always had good, straight forward & honest service from them. The staff downstairs (Doce de Julio branch) could probably do with a little bit of customer service training so that they communicate with their clients a bit more!!
If you have other questions - more specific to your personal finances which obviously you would not want to post here - feel free to PM me. ~ Grahame.
