Received a call from Ikotel regarding an "energy audit". Search of the number came up as Techno Sign & Print Inc - 13-259 Edgeley Blvd, Vaughan, ON. Obviously the are spoofing the caller ID. Caller informed me a rep will be in the area tomorrow and want's to "drop by" to do an audit at our office building. Said they were representing Essex Power. I told them flat out we are not interested and the caller got a bit harassing - asking why we are not interested, why didn't we want an audit, never shut up. Left the guy on the line for 5 minutes while I wandered around the office, he hung up when I got back.
