Would you treat a customer this way?...

I got my reply from carburetors and more, and it went something like this...

"You are blindly defending Rude non-customers. We never refused to rebuild his carb, we just refused to give him technical advise, which is both illegal and bad business. We have had this policy since 1956 and will continue this policy.We also do not sell any carburetor parts period, it states so on our website. Keep up the free advertizing. We have had the best business days since you started your boycott. Many real customers are writing and agreeing with us and buying carburetors and sending in their carburetors for rebuilds. Keep up the good work!!! Start telling the truth, though!! Thanks, Chuck"

His best business days? BS "Keep up the free advertizing"?
His response is like a grade school bully that got showed up in front of his friends by the class nerd.
Rude non customers? From what I have gathered here so far, He was rude first and now he pulls the "I'm the real Victim here" routine. "Keep up the good work"? I can almost smell the sarcasm.
How are these other "real customers" finding out about our little E-mail "Advertisments" and coming to his defense? He's full of it.
