The owner of this number left a 5"x7" card with the above contact phone number stuffed into my front door. The owner did not provide any identification of who it is. The card shows multiple business names and organizations names (the owner states that the businesses and organizations aren't affiliated with the owner) and offers the following: "HOMEOWNERS CALL FOR A COMPLIMENTARY $100 Visa Gift Card NO PURCHASE REQUIRED" n"CALL TODAY 865-863-1251" "For Homeowners over 21 who participate in a study of whole house environmental products."
