Bests & Worsts Reviews from Amazon

I bought a Swiss Diamond Cookware Set about five years ago and some of the pans that I use daily are really starting to show "wear and tear." I contacted their Customer Service Department who seemed VERY interested in helping me decide whether some of the set needed replacement. I was asked to send pictures online and full documentation on when I bought them etc. etc. I responded immediately with what they asked for! THEN, NO RESPONSE! I even sent an email to the person who originally contacted me...NO REPLY! This cookware is VERY EXPENSIVE! I do NOT recommend it because NO ONE FROM THE COMPANY answered my questions regarding whether it was SAFE TO USE IN REGARD TO WEAR!
