Appliance Repair Expert

I called this company and it took over a week for a repair guy to show. he told me that I needed a very expensive part. I agreed to hire him and paid the diagnostic fee (130) as a condition of hiring him. 5 weeks went by with no call or text. I finally had enough and called him. He then quoted me the job 300 bucks higher. I said no. I contacted another company and turns out the original repair person had the wrong diagnostic and the parts needed were much cheaper. I asked for a refund and they told me to beat it and hung up on me!
