If you feel we've failed to meet our support goal, here is how you can bring a complaint to the Commission for Complaints for Telecom-television Services (CCTS).

The CCTS is a national and independent organization dedicated to resolving customer complaints about telecommunications services, fairly and free of charge. If you have not been able to resolve a complaint about your Internet service directly with Sentex, the CCTS may be able to help.
