Slamming is the illegal practice of changing a subscriber's local or long-distance telephone service to a different carrier without the customer's explicit consent. Unscrupulous carriers historically used deceptive marketing or forged authorizations to hijack lines and charge inflated rates. Regulatory agencies strictly penalize carriers caught slamming.
The client complained about a massive bill because some shady reseller slammed their trunk lines last month.
