I got a call from this number and they said they have promotion running for home air duct cleaning and it is $49 for cleaning which you pay after the service. I asked them what's your company name, and the person told "ohh I am sorry let me give the name again, we are professional air duct cleaning". I was on the computer so I searched for that and I couldn't find what website to check. So I asked them what is your website name :). Then the person hung up the phone.

I figured that it was a fake call to get my personal information. I tried to call back to find who the person was. When I called, i get the number is not in service.
