Car Monkeys Sold me a motor that looks like it was in a feild for years Wyckoff New Jersey

I bought a motor online from this company. It is supposed to be tested and functional and have a 5 year warranty. When my mechanic received the motor he refused to even touch it. It is rusted, has corrosion on parts a cracked manifold and looks like it has been sitting in a field for years, there is even grass on it. I email about returning the motor and they informed me it had to be shipped UPS or Fedx which cost more than the motor. I sent them pictures and they still deny paying for shipping or excepting that is a peice of crap.
