Optimum equipment return - get a receipt
Return all Optimum equipment (modem, router, cable boxes, remotes) to a physical Optimum store and get a dated, itemized receipt. Mailing it back is riskier; if you must mail, keep tracking. Unreturned equipment charges of $100+ per device are one of the most common post-cancellation complaints.
If Optimum keeps billing after cancellation
Dispute the charge with your bank and file an FCC complaint at fcc.gov/complaints. Cite your cancellation confirmation and equipment return receipt. The FCC complaint forces Optimum to respond formally and is highly effective for cable/internet disputes.
