My situation is the same Hans. I won the Golf digest New Year's Shootout at the end of february, for a set of Taylormade clubs, but like you, have not even had the notification email.
Frustrating, like you say, the golf season is already well under way and it would be good to use our prizes.
But I guess it's just a case of being patient as Icon says. they are sorting prizes out, albeit very slowly..
