Level 3: Regulatory Authority (Government Ombudsman)
-
Authority: Federal Communications Commission (FCC). The FCC handles complaints related to telecommunications services, internet providers, and cable operators.

-
Timeline: You can file a complaint with the FCC at any time after attempting to resolve the issue with Optimum. The FCC will process and serve your complaint to the company. Telecom companies are legally required to provide a written response to both you and the FCC within 30 days.
Level 4: Legal Action (Final Step)
- Pre-Litigation: Before pursuing legal action, review the Optimum General Terms and Conditions of Service. Optimum enforces a mandatory Binding Arbitration clause and a class-action waiver, meaning you cannot join a class-action lawsuit against them. You may also contact your State Attorney General’s Office for consumer protection assistance.
- Court/Arbitration: If the 60-day informal resolution period (Level 2) fails, you may file a lawsuit in Small Claims Court for claims below your state’s limit. If the dispute exceeds small claims limits, you are required to initiate Binding Arbitration through the American Arbitration Association (AAA) as mandated by the subscriber agreement.
