Selway Armory Wrong ammo shipped. Wont pay return freight. Missoula Montana

I ordered 40 rounds of 7x57 mauser ammo. I receiver 40 rounds of 7x57R ammo. I contacted customer service and was informed that the order I placed was for 7x57R. I informed them I know the difference between the two cartridges, and I don't own a weapon that will fire the 7x57R ammo. They were adament that I had made the error when I placed the order. They said they would send a "label" for a return but I would have to pay freight for thier mistake. There was no "service" in their customer service! This was all my fault, and that was that!

The total freight for the original order, the return freight and freight for the correct order excedes the cost of the ammo.
