Dollars Direct is no longer doing business in Canada as of January 1, 2017. They actually stopped accepting new customers several months before this, but now they have completely wrapped up their business. Perhaps coincidentally, the Australian division of Dollars Direct also closed its doors on the same day.
Dollars Direct was the Canadian arm of Enova Holdings LLC which is in turn part of Cash America International Inc, which is a multinational financial company trading on the NYSE. Their market cap is approximately $1.09B USD. In other countries they operate as CashNetUSA (USA, payday loans), QuickQuid, DollarsDirect AU, Primary Innovations (USA, telephone microloans), and Pounds To Pocket (UK, instalment loans).
They can be reached by mail at their corporate office:
