This this is a true scammer, not just a telemarketer. The guy speaks with a heavy East Asian accent and offers duct cleaning service. The service is 10 minutes blowing all the dust from your air ducts into the home. You end up with the mess and spending hours cleaning up your own home yourself. Seniors are their favourite targets.
Air Duct Cleaning Service, Brampton. These guys are scam artists they appeared and tried to hike the agreed price by 400%. I ejected them from the house and got someone else in to do the work. Now they phone me every couple of days trying to "do me a deal". When confronted they hang up immediately. They each claim to be the business owner, who was advertised on Facebook as white Canadian, yet have Middle Eastern accents.
