So far I've had pretty good luck with Culligan Ultrapure of Albert Lea, MN. I had a bill discrepancy, I called them and they took care of it immediately with no questions asked. It wasn't a major thing, but money isn't free. After my leg surgery in July, the man who delivered the salt saw I couldn't move real well, he carried the salt down to the basement for me, then checked the salt barrel for me and added another bag of salt. Love the guys! Keep up the great work!
