User Reports

Economic Development Agencies

"I first had a man call asking all about our company moving offices. He claimed to be from the Arizona Economic Development division. He had chickens going off in the background. He was asking pushy questions and how many people worked in the office and when we were moving. I said call me back from your office, there are chickens in the background like a farm yard."

Law Firms / Police

"They claim they are a law firm for a bank and u have to pay thousands of dollars to keep from going to jail. Then got into a screaming match so I hung up and she had the nerve to call back and say I was going to jail for 5 years for not paying a bank that I never had in the first place."
