No Customer Service whatsoever

I BOUGHT 6 STAINLESS STEEL BOLTS AND NUTS AT 55 PER PIECE. OF THOSE, 5 WORKED PERFECTLY. THE ONE SEIZED EVEN WHEN GREESE WAS APP****. I THEN WENT BACK AND GOT ANOTHER ONE WHICH SEIZED TOO. THE REPLY WAS THAT IT HAPPENS WITH STAINLESS STEEL AND THEY ARE NOT GOING TO COMPENSATE ME OR EXCHANGE THE FAULTY BOLT AND NUT. MY QUESTION IS WHY 5 HAD NO PROBLEM. THE OWNER OF THE BUSINESS DID NOT EVEN MADE HIS APPEARANCE BUT THE EXCUSE WAS HE WAS ON THE PHONE. I WOULD NEVER MAKE USE OF THIS COMPANY AGAIN AND WOULD MAKE IT MY MISSION TO DETER OTHER CUSTOMERS AT HAVING THE SAME EXPERIENCE.
