I feel your anger Typhoid. About a year ago or so, I got -repped big time and it knocked me down a couple pips. I couldn't trace the person who did it, then I got into P4 and it's no longer a problem now. Because I can see who leaves rep whether they leave a message or not. So, my advice to you is just work hard and your day will eventually come.
Of course, special deals can always be made also...
