Man called and wanted to sell me duct cleaning services. I've recently had a least 5 calls from this number. He asked for the owner of the house and I answered Whose calling? What are you selling.

I told him to cross our name off the their list and stop calling. I call the number back to find the name of the company and first  got many busy signals and then it actually started to ring. It was not answered and there was no voicemail. I checked the yellowpages and could not find a business with the same phone number. The last time I called I got a pre-recorded voice mail saying the number was no longer in service! That was less than an hour after I started calling!

I'm suspecting a scam?! The business doesn't seem to exist!
