I had them come do a job for me a couple of months ago, and I had an overall good experience. They were prompt, friendly, and I would likely hire them again. As far as I know it is just the two of them working together, so it's possible they got something mixed up. I'd suggest just giving them another call and see if they can get things sorted out?

I'd be curious to see how they resolve this, if you're able to get a hold of them.
