The Morgan group Nissan Mitsubishi Bethlehem

We have order parts from The Morgan group Nissan Mitsubishi dealers in Bethlehem and had to pay for the parts before they delivery it. We **** the payment but did not receive all the parts. We phoned them and spoke to Johan Claasen who now refuse to pay us back the money that we over paid. The one part that was on the quote isn't even onbthe invoice but we paid for it.
