The woman running the hometown scrap yard is ripping ppl off who do I contact to stop this

Well something needs to be done she's rude and a thief if it's not bad enough the prices are down then having this woman stealing from customers better business borough will be called

I wish I knew....I had 25lbs of copper #2 and only got 9 or 10 bucks.... I also got there 5 minutes late and she changed to scrap price from 4.50 per hundred for tin to 1.50!!!
