(KUTV) An old scam is targeting businesses.

Shauna Greer pays the bills for CK Construction Corp in West Haven, but last year she was out for a few weeks on maternity leave. While she was out, a bill showed up from a company called IT Solutions.

The charges are for office supplies, for over $1,200. The lady filling in at first dismissed the bill, but then she got a threatening call.

“They were going to send us to collections if we didn't pay the invoice, so Accounts Payable assumed it was legit, so they paid the invoice,” Greer said.

But the payment went to a company with which CK Construction has never done business. When Shauna returned to the office she caught the error, when a second bill arrived.

This time IT Solutions double downed and wanted over $2,500.

“I was really confused because anything that's 2,500 dollars is not toner typically,” Greer said.

The company wanted nearly $600 for each toner cartridge. When Shauna disputed the charges and never heard back, she decided it was time to call 2News.

Matt Gephardt started investigating by looking at the toner cartridges themselves, finding them on nearly every office supply website.

The price? Anywhere from $38 to $70, not even close to the $600 IT Solutions charges.

2News also found IT Solutions has an "F" rating with the Better Business Bureau—and there are dozens of similar complaints about the company online.

2News called IT Solutions, but was unable to get a hold of anyone. And no one called back.

In the meantime CK Construction says they hope their expensive lesson can be a warning to others.

“They got 12-hundred dollars out of us. I’m sure they've gotten it from other companies too. So we just want to put a stop to it,” Greer said.

This is a scam that is becoming more and more common, where a company just sends you a product or a bill for a product you never ordered and insist they pay the bill.

Companies aren't allowed to do that, and legally you don't have to pay.

Best thing to do if you get a bill like that is to dispute it in writing. It will force the company to prove that you owe it.
