Sweepstake scam

I received a call from mega millions sweepstakes 18006249508 from a guy named  Zack Creigh said I won 80 days ago 3.5 million and a car but I would have to pay storage fee for the car 2,946.50 but he could take a thousands off that fee special promotions but I needed to do a Walmart to Walmart transfer to there auditor Shanley Lyle in Orange, NJ last I knew in a real sweepstakes if you don't claim your prize then it's forfeited . I wonder if he noticed I didn't get excited about winning lol
