Input: So I just recently found out that an old friend I went to school with (and am still in the same social circle as) and their spouse have been habitually selling sub par / unsafe products (of high value) in their business. It appears to be either flippant carelessness or deliberate misrepresentation of the state of the goods as it has been happening for several years. I believe it's the latter as the owner has been taken to court 20+ times for the offenses lodged by shafted customers. Despite this, they have never paid any of the money they have been ordered to pay back. Meanwhile have been living lush and ostentatiously, which now appears to be thanks to what is basically fraud.

I was really shaken to find out via a Facebook post from a customer (on a local page) who had paid several thousand and weeks later is still waiting for product. The company's ph lines are disconnected and no one responds to emails. The customer is a young family with a kid and they can't afford to lose the money they spent and its putting them in a very stressful situation.
I read their story and the story of many others and I thought I needed to help if I can.

AITA if I get my nose involved in the matter when it's really not my business? Am I wrong to use my knowledge /position as a friend to go against my friend because I feel their actions are immoral? 

Or AITA if I don't try and help those they have ripped off? Should I just pretend nothing is happening and leave it to the authorities who have so far been toothless and little helps for victims?

I'm conflicted. I just want victims to get their money back.
