UNITED NEWS INTERNATIONAL (UNI) — U.S. officials slapped a Miami man with a $120-million fine for making automated marketing telephone calls.

The fine, which was finalized on May 10, is reportedly the largest the Federal Communications Commission has ever issued.

Adrian Abramovich set up a program that made nearly 100 million automated telephone calls between 2015 and 2016 in a scam to sell vacation packages.

According to the Miami Herald, on his busiest day in October 2016, Abramovich made over two million calls. He averaged over 200,000 calls on Saturdays.

The FCC said Abramovich is the “perpetrator of one of the largest — and most dangerous — illegal robocalling campaigns that the Commission has ever investigated.”

Abramovich’s scheme pretended to be affiliated with well-known travel and hospitality companies like TripAdvisor and Expedia.
