"The CTSC dealt with complaints with respect to cable service, such as concerns about quality of service and billing until 12 April 2006, when this organisation ceased operation. Since then, complaints filed with the Commission about quality of service and billing are forwarded to the appropriate licensee [that is a cable company] for resolution."
