If the fish tape doesn't work, a "double" coat hanger should. It's a bit harder to workd with since it doesn't drop straight down, but with a little patience, it works. I know it sounds weird, but my wife & I got it to work by using a piece of wire as a "lasso" of sorts in the lower hole and hooking the loop with the coat hanger from the upper hole. Like I said, it takes patience, but it works.
