I am sorry for your trouble. My experience is quite the opposite. I have been using Bitcoin for international transfer for several years now. Not for the sake of using it, but because it works better than alternatives.

When MtGox started having problems with Dwolla, I was forced to look around for another USD option, and Bitstamp has been great.

Things you complain about have nothing to do with Bitcoin technology, but with exchanges you are using and not using, and with the current state of adoption. It's like complaining that TCP-IP is broken because your internet provider sucks or because somebody infected your PC with a virus.
