I get this number as well on occassion. I am wondering who it might be..to call it back there is no response. It reads on Caller ID as D P V I.

i have called these guys today and got my number taken off the number i called was 1-+1 800-247-3828 a person answers this number no answering machine to deal with. hope this helps

I think my search may have found this company's internet site.  I logged on and went to their 'contact' sales section and send a nasty old message telling to remove my phone number from their telemarketing scheme and stop annoying people with their nonsense.  Hope it works!!!  I'm thinking, I might just start e-mailing them daily.  Here is the URL:http://www.dominionprovac.com/

There are auto dialers for sale, Cheep. You insert an area code and it dials every posible number.

Hahaha, what an awesome idea!!!  Love that mentality, will adopt it, thanks!

I beleive their business name is Dominian Pro Vac Inc. and they want to clean your furnace. No matter how many times they call in a year and how many times you tell them you don't own a furnace, they still call. I know someone who actually booked them to come, waited all day and they never showed up.
