Query: Extremely rough cooking surface

This frying pan was unbelievably bad. The cooking surface was rougher than most cast iron utensils are on the outside. Even their website had the following:"My new Lodge Cast Iron pan feels rough in some areas, is this normal?""Yes. With use and replenishment of the seasoning, the pan will become smoother. Unlike other types of cookware, Lodge Cast Iron only gets better with use. For concerns about roughness, it is OK to use a fine grade of sandpaper to smooth out the rough areas. Make sure to re-season the item before using."I tried a medium grade of sandpaper and got nowhere with this. Very glad for Amazon's returns policy.
