The overall quality of service provided by grantee to subscribers may be subject to evaluation by City, not less often than once annually. In addition, City may evaluate the quality of service at any time, based upon the number of subscriber complaints received by the grantee and the City, and grantee’s response to those complaints. City’s evaluation that service quality is inadequate may lead to direction of grantee to cure the inadequacies. Grantee shall commence corrective action within 30 days after receipt of written notice. Failure to do so shall be deemed a breach of the franchise and subject to the remedies prescribed in this chapter. The City, after due process, may utilize the performance bond and/or security fund provided for in this chapter to remedy any such franchise breach.
