Back in the 50's there was a mail order soap fraud. A company would send a "sample" of soap. You would use the soap. A few days later a bill would come. The initial package never said it was a free sample... A federal law was drafted that stated unsolicited items sent to you were "gifts" and could not be charged for. If you have a friend who is a blood sucking leech (attorney) you might be able to screw them back, and cancel the charge while keeping the gage.
