Didn't seem to know what he was doing

I arranged for him to come & service/repair an old gas fireplace. I knew a couple parts had seized due to an old water leak. He whined & complained for an hour and a half. What I was left with was an expensive bill, and nothing else. No estimate of new parts, he wasn't sure if he could adapt parts. Rather than throwing good money after bad, I got someone else. It was very frustrating and I couldn't wait for him to leave. Useless!
