You don't describe what the allegedly hostile interaction was, but many manufacturers prefer that the dealers handle the customer service aspect. I don't know you or what you expected from this company, but some people expect a manufacturer to provide free repair out of warranty or things like that. There are some companies known for outstanding customer service and perhaps you should only deal with them.
Hostility from manufacturers
I know its a cottage industry, and margins are thin, but I still think its shortsighted of them, and harms the industry in the long run. I'm talking about several interactions I've had with manufacturers after having purchased their products on the secondhand market. They should think about what would happen to their prices and their sales if their products were not resellable. Maybe they would like us to send our components to the scrap heap every few years or so just before we purchase their latest upgrade.
