Does anyone have any Kirby Salesmen Horror Stories?

A FEW YEARS AGO, MY SON BOUGHT ONE FROM A FRIEND WHO WAS SELLING kIRBY'S, HE PAID SIX HUNDRED DOLLARS FOR THE MACHINE. WHICH WAS AT OR NEAR COST. HE WAS PROMISED A SHAMPOO ATTACHMENT THAT HE NEVER RECEIVED. A SALESMAN IN THIS AREA GOT INTO TROUBLE WITH THE LAW FOR PREYING ON OLD LADIES. THEY HAD TO BUY TO GET THE GUY OUT OF THE HOUSE.
