Scams
I have had many of the above scams The one on Social Security is a great one. I called our local SS office and she told me that they NEVER call only mail. She also told me that somehow they manage to use their phone number.
I have also been lucky not to be scammed on Craidslist. They want you to send them the item and they will send you a check for the item plus shipping. Although, the check is NO good!
