They have a third party customer service call center. I had a problem with a shifter knob. Color was way off. Had to talk to several people to get a full refund. Bastards wanted to charge me a restocking fee.
I do the same with summit racing, they are about a 45 minute drive. And summit motorsports park is about 45 mins also in the other direction.LMR is less then a 2hr drive from my house. Might make a day trip and give them my money.
It would be a poor me story if trying to get something for nothing or even a reduced price. The narrative never has been either. Having working on the business and operations side of automotive manufacturing 30 years, I learned what a few concepts that work in sales and service, and what may not. Balance between the two is important for a successful business. One can get great short term results focusing too greatly on one aspect. To your very, very good point, proof is frequently lacking and/or truth misrepresented when people want something for nothing or at a reduced price.After over a year and finding a problem, put yourself in their shoes. How will you prove the defect is not the seller's or the buyer's fault?
That is a long poor me story, but you need to do your own bidding?
