I just used Jen's advice and they confirmed that our number was on their list and they will take it off. Thanks, Jen
"Just call Concord Technologies out of Seatle, Washington (800)792-0329. They will say they don't have (312)962-4125 listed to them. Give them your phone number(the one they are calling 50 times a day) to search their database. They should get a hit for another company they do faxes for. They will tell you they don't have access to that company's database but should offer to contact them on your behalf to have your number removed.
Our business started getting calls yesterday from this company. I called Concord Technologies and was able to have them look up our number as well. Thanks to all for the information on this number.
