Canton runs this business-service division of Excel Communications. Excel is the king of “pyramid” long-distance phone marketing, in which people receive commissions for persuading others to switch to Excel’s phone service and then recruiting salespeople of their own. This sales network has a high turnover rate and limited experience, which has spawned problems with customers being illegally switched to Excel without permission (the federal government and Pennsylvania cracked down on such Excel “slamming” in the late ‘90s). Disillusioned salespeople also have had trouble getting refunds from Excel after they quit. Excel was temporarily expelled from the Better Business Bureau in its hometown of Dallas in ’96 in response to more than 100 complaints.
