Pennsylvania Golf Carts

I was in search to purchase a golf cart. I emailed this company and asked them nicely if they would accept $2500 for a golf cart they listed. They wrote back that I insulted them with my offer and because of this they will never sell me a golf cart. I emailed back and said they were very unprofessional and that they should respond nicer for better customer service and they emailed back and told me to go F myself. This is a very unprofessional business and to be denied business because my offer was too low is ridiculous.
