Cramming (fraud)

Cramming is a form of fraud in which small charges are added to a bill by a third party without the subscriber's consent, approval, authorization or disclosure. These may be disguised as a tax, some other common fee or a bogus service, and may be several dollars or even just a few cents. The crammer's intent is that the subscriber will overlook and ultimately pay these small charges without challenging their legitimacy or inquiring further.

According to the U.S. National Association of Attorneys General, cramming was the 4th most common consumer complaint of 2007 in the United States.
