You may have hit the magic number of 100 refunds like I did. My apple ID is locked, no purchases no more refunds and no downloading even free app's. My 9000 songs and movies purchased over the past 16 years are gone, they can't be transferred to a new ID. At first I was upset, then I got a bit upset when I realized Apple was keeping my money and flipping me the bird.
