The truth is, LEO don't give a shit about these types of crimes, because the CC companies have the fraud already built into their business models (e.g., they've priced in losses).
I suspect CC companies refund the ones who complain, but enough victims of smaller scams never complain and thus it pays off.
What would help is shared liability, and mandatory full refunds for all victims, not just those that come forward. For example, a consumer protection agency or association could prove that a certain company was scamming, and get a court order forcing the payment companies to reverse all transactions associated with that company.
Suddenly, all those "FREE SUBSCRIPTION *turns into a $49/month, 6 month minimum subscription if not cancelled within 7 days" (with the "free" repeated in huge letters and the subscription terms hidden in the finest fine print) scams would become risky enough that the payment providers would no longer be happy to enable them for a small percentage of the loot.
The whole thing is automated, from asking for a donation, asking you to send it with a credit card vs a letter in the mail, to telling you 'oh I'm a real person' when CLEARLY they're not (or they all talk the same... /s).
This money goes somewhere. It's the same voice. It's the same scammer. Nothing is being done about it. You'd think some breast cancer organization would sue them to make it go away.
