Optimal Collection & Tracing Services is a Collection Agency based in Burnaby, British Columbia, Canada.
Many of those who work as Debt Collectors are not polite because they are not Boy Scouts and/or Girl Guides.  They are mainly a downtrodden lot, and their ranks include ex-convicts, drug addicts, 20-somethings without high-school diplomas and a variety of other hard-luck cases.
Oh, my Gawd, they are like thugs.  However, the more clean-cut types simply can’t get the job done.  So don't expect that debt collector, who is calling you, to be nice!!!

Harassing alleged debtors and calling them names, threatening them with lawsuits/arrest/jail - all illegal.  You're right   about one thing, though - no one here cares about your sob story for debt scammers!

The correct address is, and should read...  #206 - 3989 Henning Dr, Burnaby, BC V5C 6P8
and not...   #206 - 989 Henning Dr, Burnaby, BC

Are you advertising for that company?
If not, why post that address information here?

Perhaps it would be better if you posted links to the various Canadian debt collector regulations, so other Canadians could learn how to defend themselves, if they receive calls or emails from supposed debt collectors!
