This man, Cliford is a liar and insane. I have never met someone so rude and obnoxious in all of my life. When I tried to give him directions to my vehicle and address, he interrupted me to tell me he was very familiar with the area. Once he got lost and drove around for half an hour(because he didn't even know the address, obviously) he got violently angry, very much treating me like I was stupid. I couldn't even get the words out to tell him where I was because he was SO intent to make sure I knew it was my fault he was lost. Unable to help him through his violence and anger, I just walked half a mile up a road to find him. Once I was able to get him to where my vehicle was located, it was a disgusting montage of this man treating myself and his assistant with horrible disrespect. My battery was dead, he refused to charge it less than two minutes, SPRAYED STARTER FLUID INTO THE AIR COMPRESSION CHAMBER OF MY DIESEL ENGINE because he was too lazy to do his job properly, then charged me 125$ even though he had already been paid by my roadside assistance company, and most of his time he charged me for was spent wandering around like a lost idiot because his ego couldn't be bothered to listen to directions. This man is a crook, and I will be filing a report and looking into his licensing. It doesn't make sense that a licensed DIESEL mechanic would spray starter fluid in an engine. He has no idea what he is doing, but he'll make sure he treats everyone with violence and disrespect while doing it. The police will most likely be contacted about this incident.
