An Arizona company suspected of making illegal telemarketing calls for more than a year was fined $37.5 million, the Federal Communications Commission announced Wednesday.

Tucson-based Affordable Enterprises of Arizona made about 2 million telemarketing calls to sell remodeling and home improvement services during a 14-month period beginning in 2016, according to an FCC news release.

The company is accused of spoofing or manipulating the caller ID to people's phone numbers so consumers could not identify that the calls were from Affordable Enterprises, the FCC said.

"One Arizonan received more than five calls per day on her cell phone from consumers complaining about telemarketing calls they thought she had made," the FCC said in the release.

A former employee of Affordable Enterprises provided the information to the FCC's Enforcement Bureau which subpoenaed the company's phone records and reviewed consumers' complaints from the national Do Not Call Registry.

Affordable Enterprises is suspected of violating the Truth in Caller ID Act which prohibits transmission of misleading or inaccurate caller ID identification with malicious intent, according to the FCC.

They are also suspected of violating the Telephone Consumer Protection Act, which prohibits telemarketing calls to numbers on the national Do Not Call Registry.

The FCC proposed issuing the Notice of Apparent Liability Forfeiture fine.

"This is the commission's first major enforcement action against a company that apparently commandeered consumers' phone numbers," the FCC said in the release.

Affordable Enterprises will be able to provide evidence and legal arguments before further action by the commission.
