I have received a message from this individual as well. When I returned his call, I left a message telling him that there was absolutely no reason for him to be calling me (because there isn't) and that I didn't want him to call me again.
I keep getting a phone call from this man saying his name is officer don williams. He is very rude and keeps calling my work. I know its not legal and he is very fishy. I promised to pay him and he wanted me to use this card called a money pak card and not my debit card. Saying that it was illegal for me to use my debit card. I already paid 150$ to him and I aint giving anymore to him I am done messing around. I am glad I figured it out before he put me in a hole.
