Definite scam. I did not get a call but I got a check in the mail,  I called the number and asked to speak with the person they had as a contact person but he was not available .  The person who answered the phone said he can help me.  He asked for my name and the claim code and told me to deposit the check then call them back.  I wanted to know why I have to call them back and he said he'll give me more instructions at that time.  When I insisted on knowing the whole procedure, he hung up.  I called back and got him again and this time he was nowhere near helpful.  When you see the check, don't bother calling them, just toss it out.
