Frontier

In short

Frontier is now a Verizon company, and its customer service and technical support run through chat, not a published phone number. Dispute a charge within 30 days after you receive the bill; a bill becomes final if Frontier gets no dispute within 90 days. Return equipment within 30 days of disconnection or pay up to $500 per device. Under a 2022 settlement with the FTC, Frontier agreed to back up its internet speed claims and to let DSL customers who get far slower speeds change or cancel for free.

How complaints actually go

• Frontier lists no phone number for customer service or technical support; both go through chat on the contact page (automated 24 hours, live agents in business hours). A Spanish-language line is 1-800-921-8103. Frontier contact
• To dispute a charge, use the MyFrontier app: My Billing, then "Get help with your bill". Frontier: disconnecting your service
• The general terms tell customers to dispute charges within 30 days after receiving a bill, and say a bill cannot be challenged further if Frontier receives no dispute within 90 days. Frontier general terms
• Written notices go to Consumer Relations, Frontier Communications, P.O. Box 5156, Tampa, FL 33675, with a copy to Verizon's Legal Department. If Frontier does not remedy a breach within 30 days of your notice, you may terminate; the remedy is termination or a credit of no more than 90 days of charges. Frontier general terms

What tends to work

Scams that target customers

• No current Frontier page on scams was found. The FCC warned on September 10, 2025 that scammers offer "50% off" internet and cable bills and then demand prepayment with gift cards, and says to contact your provider only at the number or email on your bill. FCC alert
