The Brazilian government is concerned that some hotels listed on FIFA's website for the 2014 World Cup plan to overcharge during the tournament.

Brazil's tourism board has notified the justice ministry after one of its studies showed that rates will be up to 500 percent more expensive during the World Cup in some hotels from the agency MATCH Services, which is listed on FIFA's website.

The board says "it's probable that MATCH is exercising intermediation fees that are a lot higher than usually exercised in the tourism market."

MATCH denied any wrongdoing Saturday, saying it "provides a totally transparent price structure."
