Truck body repair service near Marshall, MI

Went to south street auto salvage to get some parts for a car im restoring, got the parts i needed and inquired about a grille for the vehicle. They found one at a different salvage yard in lansing and told me it could be here monday (it was thursday afternoon when ordered), i asked how much? Was told $40. So i bought the part plus the grille in which they didnt have tehe change to break a $50, so they owed me money was written on the reciept. By wednesday the following week went by, i hadent heard anything, so i stopped up there. Nobody had seen the part come in so they called Golden's shop to see if it went there (ges the owner of both shops), it didnt arrive there either. So they asked me to wait a few days while the found the part. Friday came, still no word, they "shops" had no idea where the part went. The associate who i had been dealing with the entire time called the owner at that point, they were on the phone for awhile and then came back. The associate told me since i had been jerked around they were ordering me the part new. I mentioned that no, i didnt want to pay the difference which is why i was at the salvage yard, in which i was told i am not paying the difference, that id be getting it for what i already paid. So i said fine, the part was ordered and showed up the following monday at Golden's shop. I went to go pick it up and they refused to give me the part unless i pay the difference. So i explained the story to the person at Golden's shop, they called the owner and he denied the story "which i was right there and heard the two talk on the phone the previous friday". So i wanted my money bac, since i was being dicked around yet again and they yold me no! I get no money back, i get credit twards something only. This upset me more because as i mentioned in the beginning they couldnlt break a $50 and owed me change back, it was written on the receipt and signed by the employee.
