An Alberta court has sentenced five individuals for their involvement in the Ambus Registry Inc. deceptive telemarketing scheme, the Competition Bureau said Tuesday. The Competition Bureau led an investigation that found, over a three-year period, Ambus telemarketers used an “assumed sale” technique to defraud more than 10,000 businesses, government agencies, educational institutions and not-for-profit agencies in the United States. The technique involved a sales pitch that led telephone recipients to believe that a sales had taken place and that their business was legally obliged to complete the purchase, the bureau said in a release. The Competition Bureau said Ambus’ fraudulent operations are estimated to have grossed over $3.75 million in losses for victims and businesses. Garther Cheung and Sukhraj Singh Chana, co-founders of the company, received one year each in prison for three counts of deceptive telemarketing. They will also be required to serve two years in a federal prison—a result of committing fraud over $5,000, the bureau said. Pritpal Chana and Ranjit Sangha, the managers of Ambus, were each sentenced to 16 months each for three counts of deceptive telemarketing as well as 16 months for committing fraud over $5,000. Andrea Kyweriga, a manager who was convicted of two counts of deceptive telemarketing, received a suspended sentence and two years' probation. Sarah Schaefer had previously pleaded guilty to charges in 2007 and received a $15,000 fine, the bureau said.
