A common type of deceptive business practices involves contacting people via telephone to attempt to sell them a product or service that has little or no value, or perhaps does not even exist. Such schemes are often called telemarketing fraud and may be investigated by both state and federal authorities. At the federal level, such activity is investigated by the Federal Trade Commission. While the Commission can find and investigate such schemes of their own accord, it is common that citizen complaints to the FTC are the basis for instituting most telemarketing fraud cases. At the state level, a similar process may be available, administered by the state attorney general’s office or a special consumer protection agency.
