How does this merchant stay in business? Why does their bank let them make fraudulent charges to their customers?

That is i am wondering.

I've been researching this an part of his tactics is that he maintains multiple companies (Office Machine Depot, Ace Depot, Poppopoffice, Paper Monster) are all versions of the same operation. He also keeps changing credit card processors. Website claims to use Authorize.net but they terminated him back in 2018. He's now with First Data. What'll he do next? It is time for law enforcement to stop this guy from further abuse.
