Poor service, No invoice

Dan Appliances came out because two plates on my stove were giving problems. The technician did no diagnosis and simply replaced both plates, despite me repeatedly asking how he knew they were faulty. There was no testing equipment. The plates were replaced, but the problem remained. I was then told it must be the switches.

Long story short, the stove is now fixed, but the seal around the stove was damaged during the repairs and needs replacing. I’ve contacted Dan about this, but he doesn’t answer my calls or respond to my messages. They need to come back and finish the job properly.

I’m also still waiting for the invoice I was promised.
