76 Subscriber Agreement: General Terms and Conditions of Service
exemption, you must provide us with a valid exemption certificate. Tax exemptions generally
won’t be applied retroactively.
Surcharges
You agree to pay the surcharges, fees and other charges that we assess to recoup our
government costs or costs of complying with certain government programs (“Surcharges”).
Surcharges aren’t taxes or government mandated charges; they’re charges we choose to
collect from you. Surcharges are subject to change, sometimes on a monthly or quarterly
basis. Examples of Surcharges include, but are not limited to: Universal Service Fund, E911,
Federal Programs Cost Recovery, Federal Wireless Number Pooling and Portability, and gross
receipts charges. We will make efforts to provide you notice of any changes to Surcharges in a
manner consistent with this Agreement (see “Providing Notice Under This Agreement”
paragraph). However, since most Surcharges are based on amounts set by the government or
based on government formulas, it will not always be possible to provide advance notice of
new Surcharges or changes in the amount of existing Surcharges. Information on Surcharges
is provided during the sales transaction and is available at our Web site.
Disputing Charges - You Must Still Pay Undisputed Charges
Any dispute to a charge on your bill must be made within 60 days of the date of the bill that
initially contained the charge. Disputes can only be made by calling or writing us as directed
on your invoice or elsewhere. You accept all charges not properly disputed within the above
time period – undisputed charges must still be paid as stated on your bill.
