got a letter from "SWEEPSTAKES" with a check of $4980.00. must be a scam.

I did too, I'm wondering if its a scam? Did you call them?

I called Collins James and he has a heavy middle eastern accent. He wants me to deposit the check for $4,980 in my bank and then send a money gram from Walmart to the tax agent. This must be a scam. The tax agent listed is Mary Walker but she is on vacation. He wants me to send a money gram for $3,990 to Sebit Dada. I'm calling the authorities to check this out.

I too received this letter.  I have confirmed that it is a fraud.  If you do not believe me, you can call Ruby Leather Co.,INC and they will inform you.

SEBIT IS NOT A SCAM SOMEONE IS JUST USING THE NAME FOR SCAM.THEY PICK UP ANY NAME AND USE THEM,THAT IS HOW THEY WORK.
