Caller: Some Paki dude for Duct cleaning

This is some Paki dude who keeps calling for Duct cleaning anytime he calls which is about three times a week and says that the duct cleaning is taking place around your location and if i was interested in cleaning the duct of my home. Once I mentioned i am living in Milton and he says that the cleaning was to take place the next day and promised me duct cleaning at a discount of $100 tomorrow at 11 am and whereas I live in scarborough so you know these people are scamster beware of any such calls for duct cleaning especially from people whobehave like Canadian but their speech gives them away as they talk with a typical paki accent.
