VERY BAD SERVICE AND CUSTOMER RELATIONS!

I asked for snuff for a snuff canon and was sold snuss. When I returned it the next day I was told they dont sell snuff. When I asked the owner to give me my money back as did not ask for snuss I wanted snuff he refused. He told me to go sell it online. When I told him that I will never buy from him shop again he told me told me to not come back and started yelling at me to get out of his shop. I have never been humiliated like this ever. I gave him the snuss seeing that I had no use for it, and he is obviously desperate for sales and does not have the money to give back as I was the only customer in the shop on both days I was there. I can see why its because of the way he treats customers.
