An Air Duct cleaning company. I have been called twice in a week. In the first call, a lady of the company said one of my family members called her and she was calling us back. Actually, it was not true. I am in Ottawa.
These guys called Jul 24 and 26th. I am in Ottawa, the 613 area code is in Ottawa. Unfortunately there is no way to determine if this is a legit call or not until it is answered.
