Just called, and after I said "hello?" a couple of times, I got what sounded like a boiler room, and some [***] said some kind of gibberish. I asked him (rather politely, I thought, considering I knew the score) to speak American English. He hung up! Imagine that!!! Golly, gee whiz!
I love to mess with these guys when I have nothing better to do. Of course, added to my personal block list.
