Smith Brothers Appliance Repair Ripped Off- $400 repair for $12 part - Dishonest, Beware of this company orange, California

Maytag fridge went out after 5 years. 'OC Appliance Repair" was the first I saw on the google, so I called them and made an appointment the next day for $65 to inspect, which is included in the repair if I used them.  The Smith Brothers guy comes on time, and says "you hear that click?" I said not really but ok, and he said I needed a new Hard Start kit. The kit cost $249, plus $149 to install it and tax. Well, it is just barely below the price threshold of replacing the refrigerator so I said ok. He walks in with a part, unscrews the cover off the back, busts something out of there, installs the part in 2 minutes and says "it's done".  All total, maybe 10 minutes.  

I'm stunned and feeling like I got taken, but paid the bill and he left.   I pulled the refrigerator out, took the cover off and looked at the part. I took a photo of it to get the brand (a supco rco410 3-in-one capacitor) and looked up on Amazon. The part is $11.95. So, what should have been $65 + maybe $50 for parts ($115 is fair for the time overall) I paid $410.

I have contacted the company (which looks to me is really just an answering service) so we will see if I get any response.
