We took an ATV tour in Ensenada booked through Viator. The operator did the whole equipment damage accusation thing, despite the fact that nothing was damaged by us and the brakes did not work on the equipment.
He actually grabbed my husband’s wallet out of his hands and took all of our cash, about $80. Viator investigated and agreed with our account, but did not refund the trip cost (about $160), only their $20 service fee. And they continue to do business with that company.
