do you know a Tom or have you been in any type of correctional facility where you had a pen pal?

A girl from this number called my 13 year-old boy and talked very dirty. I was on the other phone and asked her who she was, she hanged up immediately. I called back, she answered using a faked voice. I'll repor this incidence to police.

I received call from this no. They said they were from Wal Mart and I have won alot of money from a contest.
All I need to do was to purchase a M Dot card for Two Hundred dallars.  Then they would deliever my money.
When I told them I didn't think this was legit and hung up they kept calling back at first started a message but did not finish it.  Then they call four more times but did not leave a message.
