It may be that you or someone in your household has used a pay-per-use feature. Since you're only charged for pay-per-use features when you use them, you might not be accustomed to seeing them on your bill. These appear on your bill under the "Usage Charges" section.
For your phone service, they could include:
- Directory assistance (i.e. "information" or 411)
- Last call return
- Continuous redial
- 3-way calling
For your television service, they could include pay-per-view selections such as movies, video-on-demand or special events.
