ACN Porting number charges Concord North Carolina

After completing a two year contract for phone service and a couple thousand dollars in equipment with ACN our number that we owned prior to the company was ported to another service provider. We received an unexpected port charge for porting the number. I contacted the company and made a request to verify the port charge in the terms of service contract that was agreed upon two years ago. The customer service representative was unable to verify nor was she able to provide me a copy of what was agreed upon when service was activated.

Here is another example of additional fees that ACN is charging their customers:

Effective June 1, 2013, you may notice a charge on your monthly invoice labeled Compliance Cost Recovery Fee in the amount of $1.99. This fee is used to recover costs associated with compliance of local, state and federal tax requirements, as well as those associated with anti-fraud protection, number portability, emergency 911 support and customer privacy protection.

This fee is not a tax or charge required or assessed by any government. The Compliance Cost Recovery Fee will apply to every telephone line assigned, including toll free and virtual numbers. Surcharges, taxes and fees assessed by ACN are similar to those charged by other Telecommunications and Digital Phone Service (VoIP) providers.

It seems like ACN may not be in compliance with all the requirements.
