I really don't know - I can't give any insight into the finer details concerning this particular product, as I haven't researched who holds what in terms of trademark etc, or the specific selling restrictions that are in place; I can only provide some of the possible reasons they objected to the listing, and some general information as to how / why these sorts of rules exist. 

Best thing to do is try to get a response from the company, they may not object to a listing under certain conditions (presuming they have used their Vero membership rights correctly).
