Express Rooter Plumbing

I called Express Rooter given their ratings when my shower handle stopped working. One of their plumbers came and fixed it quickly. I was happy with his speed, knowledge and personality but not happy with how he left my brand new, very expensive cartridge/handle system. He used a wrench to tighten it without anything between it and the fine metal and it scratched it up to the points where the metal covering is missing. It looks terrible. He made no apologies and when I emailed the company with a photo of it I did not receive a signal reply. Very poor customer service.
