This looks like a great time to make reports and providing proof would be a nail in the coffin for those service providers to take notice of, as well as knocking the scammers of their pedestal for a while. Reporting to the service providers of scammers using their services will be taken much more serious now, so report away!
If the Service Provider doesn't act and the number is still active, then report to the FTC and FCC. Personally, I would report to them anyway so they are aware too.

The Federal Communications Commission and the Federal Trade Commission have warned telephone companies that serve as gateways for overseas calls to stop forwarding coronavirus-related robocall scams.
The agencies sent joint letters to three U.S. gateway providers – they act as onramps for international calls into the U.S. phone network – demanding they cut off robocalls designed to take advantage of consumer fears about the COVID-19 virus.
The FCC and FTC gave the three companies – [b]SIPJoin of Suffolk, Virginia, Connexum of Orange, California, and VoIP Terminator/BLMarketing of Lake Mary, Florida[/b] – 48 hours to stop "routing and transmitting" the calls into the U.S. or "face serious consequences," the agencies said in announcements about the action.
