Sigma lenses are mount specific.
If you have a nikon mount, it won't fit or work with your 80D (period).

You don't understand. You don't get a mount for a sigma lens. Some lenses come as Nikon mount, and some lenses come as Canon mount. You cannot interchange them.
Switching mounts is something the factory would have to do, and I don't know if they can.

"There is no way to adapt it."
Actually there is....
"All lenses from SIGMA's new three product lines (Contemporary, Art, Sports) will qualify for this paid “Mount Conversion Service”. It enables customers to convert the mount of their current lenses, and we will change the relevant parts for a different mount and its internal core system accordingly."
Sigma has offered this service for some time now. However, I hope the OP knows or realizes this is not a free service. The OP is far better off to return the lens and buy the correct one. Plus the OP needs to find a more honest or at least knowledgeable dealer.
