Slamming and cramming

Slamming and cramming involves third-party charges to your bill without your knowledge or consent.

What's the difference between slamming and cramming?

Slamming occurs when a telephone company changes your service provider without your consent or knowledge. Slamming methods can include: “free trials” signing up for marketing promotions without reading the fine print and offers for credit cards or giveaways.

Cramming is a form of fraud in which a company places unauthorized and miscellaneous charges on your bill. This could involve a charge for a voicemail service, Internet access or other service charges.

Tips to protect yourself against slamming and cramming.

Don't sign up for marketing promotions without reading the terms and conditions before signing up for anything that will be charged to your landline or wireless telephone service.

Review all your bills carefully and make sure you understand all charges. Be on the lookout for unfamiliar company names, calls you did not make and services you did not order.
