Hello Rosa,
I had this happen to me when trying to sell Chanel cosmetics, there is absolutely nothing you can do. You basically will be allowed to list one or two every few weeks till one day ebay will miraculously allow you list more, eventually the restriction will be removed. I think it took me 4 months before restrictions were removed, it all depends on how much other stuff you sell and your feedback i think. Ebay would not disclose the criteria.
