Is this a reason to not a get a raise?

I've worked on cars for 7 years. I worked for Toyota for 3 years and Honda for 4 years. I'm and ASE certified master and Honda certified long story short the GM at the Honda dealer fattened up the shares ran the dealership into the ground with dishonest ethics sold the shares and just quit. We have a bad rep and no work now I found a job at an Acura dealer that was expanding The service manager told me he would pay me $13.00 I was at $22.00 to over see the quick lube UN till my bay was built. Then i get my raise and normal roll back My bay was built he put some other guy in it he hired from an outside source. He started giving me regular mechanic work after a week of it told him I won't do it until he pays me. He told me I need to prove to my self to him. I told him I have 7 years of experience and certified and I've done what's he's asked for the past week and ran his express lube for 3 months which are all thing that nobody can just walk off the street to do. He told me I can use my skill set, credentials, or experience as a way to get a raise or a promotion. Like wtf.
