Appliance Repairman

I paid $280 for the repairman to open my stovetop and find out what was wrong. I was told that that would pay for the repair but additional parts might be more. Once he determined that I needed a new switch I was told he would get back to me in an hour on the price. Then he told me there would be cost to install the new part as well. Never heard from them again. After 3 days I called and was told they were having trouble finding the part but they would expedite the process and get back to me ASAP. Now three weeks later, I am out $280, my stovetop still isn't working and I have heard NOTHING from this company. I would NEVER use them again.
