A number with a '359' country code will ring you up real fast, so fast that you can't answer in the hopes that you'll be stupid enough to call back.
Then they, usually women, lure you in with a sob story, usually of family strife and financial difficulty hoping to swindle some unsuspecting, naive and hormonal Turkish guy out of his money. Hook. Line. Sinker.
Its been going on for 4 months now and happens every few weeks. I'm hoping to one day catch it in time and answer. In the meantime, I'm going to brush up on some Bulgarian expletives if I have to.
