Best Cabinetry in Milwaukee WI

Needed my hot tub repaired. Tech was very polite and solved the problem. The problem is when I got the bill they overcharged me 1 hour in tech time. I have video proof of when the tech arrived and left, but they refused to adjust their bill. Additionally, the repair part is available from multiple sources on the Internet for $170, but they charged me $218, a 28% markup. I will find a different plumber for future work.
