mega millions clearing house you have won $475,360.00 and a check for $2950.00 call before depositing and then call after depositing salem, Oregon

Ok i received a letter today stating that i had won $475,360.00 through the mega millions clearing house and along a check was in the letter for $2950.00.  There was number to call a Eric Gibson (1-778-288-2178) I called he tells me the check is real and good just deposit it and call him when i do.  When i asked was this a fraud he said no and the the rest of the money i will received in five days through UPS.  I thought about looked it up on the internet and seen scam and thats why im filing this.  They need to be sued and locked thats terrible.
