I have received calls from this number both on my landline and cell.  They have never left a message so I called it and was told if I answered just a few questions that I would qualify for a $100.00 pre-paid Wal-Mart Card, the questions were not asking for personal information, HOWEVER in order to receive the Wal-Mart card there was a $4.00 fee and they asked for a checking account number (I lied and said that I didn't have one!) then was told "Oh that's OK you can charge it to any credit card and it will only be a$1.00...................... Duh like I'm going to give them my c.c. number, I just hung up.
