North Carolina - Breach of Contract

[Rogean]

Can someone find me specific law, either North Carolina or Federal, that protects a party such as a consumer, from breaches of a contract by a company.

Specifically, part of the contract was removed, and the company thinks its ok to just remove the associated cost and still bind the contract's yearly auto-renewal, forcing me to keep paying for a defunct service that I can no longer use for several more months.

Looking for any specific law quotes that I can use against them.

Thanks.
