inspect before purchase and fix light

I am so disgusted with this shop, I purchased a yamaha r6 from my friends brother and I took it here to have it checked out before I purchased it and to have the bike lowered. The headlight did not work, he said that it was wired wrong and I needed a new relay. That was suppose to be the only problem. I did not know how to ride my bike at the time, so he took over a month to fix these things. but he was constantly working on someone else's bike. He never returned my calls I would have to call multiple times just to get an update. He finally finishes my bike and i get it back, I still didn't know how to ride so I would just move it around in my garage so my new tires wouldn't get messed up. Around 9 months go by and I have time to take the class to learn to ride, after I finished my class I get home and put a new battery in my bike go to start it up and, BAM!!! the gas just pores out of my bike plus the lights don't work. So I put it back in the shop, not this one of course. and come to find out he has wired the light wrong and it burned out my brand new relay so I have to buy another one. plus I have absolutely no rear breaks. Thank God I did not know how to ride when he so called fixed my bike and inspected it for me, cause I would have probably kilt myself thinking I had breaks when I didn't. If you are not one of his buddies I would not suggest using this shop, the service is poor and clearly the quality of work is subpar.
