More than 1,000 businesses in Columbia are at risk of a billing scam.
The Chamber of Commerce is warning their members to watch out for an Illinois-based advertising company called Admosphere Advertising.
The fake company sends invoices to businesses that have advertisements in the Chamber of Commerce's magazines and directory.
The company is even going as far as printing fake advertisements trying to trick the business into thinking they actually advertised.
"There was an ad that clearly wasn't an ad that I had created and it had our old logo on it, so I could tell it wasn't something I had created," said Michele Batye, financial officer at David Griggs' Flooring America.
Batye was not convinced that Admosphere was working with the Chamber of Commerce like they told her, and she was right.
"This one is a little fishier than what I've seen in the past just because we can't find them online and we can't find anything about them," said Matt McCormick, president of Columbia's Chamber of Commerce.
ABC 17 News looked up Admosphere Advertising Thursday and found no website. Instead, there was an address that led to the middle of a residential area.
McCormick told ABC 17 News this is not the first time something like this has happened.
"We probably see about half a dozen in a year if that," said McCormick.
