Yep, he did hit something. Besides, Pro comp themselves isn't usually responsible for that stuff. The dealer who installed it is. Pro-Comp is a high quality tire and they have good reason to follow company policy on these matters.
As for the woman on the telephone, however, no excuse!
I am so doggone tired of almost every business treating customers as if they are an inconvenience.
Even if your friend was an a$$hole, her conduct was inexcusable.
I have dealt with customers in many different venues and capacities over the years. The ones who are pissed may or may not have a good reason to be. They may or may not be nice. They are almost ALWAYS easy to please. If they are shown a little effort and they will generally be happy that the CSR has done there best to rectify the problem.
I boycott EVERY business that shows me poor customer service (unless management rectifies it). I also try to report infractions. If everyone did that none of these jerks would have jobs. If they did, then the businesses keeping them would go under.
I don't ask for much from the businesses that I spend my money at. Just common courtesy. If they can't handle that, there are plenty of other businesses out there who actually want customers.
Porsche996: Tell your friend to write a letter to somebody high up in pro-comp about everything he has experienced. He should be sure to cc the board of directors. I bet he will hear back from them, promptly.
