IANAL (thank G) but depending on the laws of your state, Small Claims court may be the way to go. many people ignore the summons, plaintiffs usually seem to get a default judgment that can't be appealed, you can then slap a lien on the person or their property to have the judgment filled. if it's not paid, then it usually collects interest at an annual rate set by the state.It seems I have to do most myself when I can and sometimes even when I can't I have to try and figure it out because I can't seem to find anyone who you can trust to do the work correct. They don't mind charging a nice price for doing quality work but then when you find out the hard way like I have in the past it just sucks knowing that is the kind of work you are paying for. My last one is posted on my Facebook page (facebook.com/eddie.grimes.56/) and is pinned at the top so no searching for it if anyone wants to take a look at what I am referring to it is all very well documented with pictures, receipts, dates, and facts from manufactures etc and to this day he still denies it was done wrong. Thinking about going to small claims court but as of yet I have not. I did go through the BBB and the Attorney General which was both just a waste of time and paper as neither did absolutely nothing at all to help. This is pertaining to a 81 F100 I own. So yea if at all possible I do it all myself and even some things I am not sure about I try to read up on and do that also. Exhaust shops in particular are a no go for me anymore. Considering purchasing my own tire machine and balancer but as of yet I have not. Anyway if you have found someone good and can trust them hope you have better luck than I have had in the past with recommended shops.
