Check for an outage before you call: service status page.
Step two
Work through the stages in order. Each one creates the paper trail the next stage needs.
Stage 1
Straight away
Contact AT&T and ask for the issue to be logged as a formal complaint. Get the complaint or ticket number, and ask what outcome the agent can authorise.
Use the phone, chat or online complaint form on this page.
Ask for a supervisor or the loyalty/retention team if the first-line agent cannot approve a credit.
Stage 2
Allow 7–14 days
Email or use the provider's complaint form. Summarise the facts, the amount in dispute and the remedy you want. Give a clear deadline for a response.
Attach bills, screenshots and a simple timeline.
Written complaints are easier to attach to a PUC or FCC filing later.
Stage 3
After the provider has had a chance to respond
Your state PUC handles complaints about telecom service, billing and safety. Many accept complaints online and require the provider to respond.
Find your state commission and file a consumer complaint with your evidence.
Ask the PUC whether your issue is within its jurisdiction; broadband-only services are handled differently in some states.
Stage 4
Any time, but sooner is better
The FCC accepts informal complaints about phone, internet and cable service. The provider must respond, and the FCC can use patterns of complaints in investigations.
Use the FCC Consumer Complaints Center and include your provider reference number.
The FCC does not award damages. Use it alongside, not instead of, the PUC or small claims.
Stage 5
Check your state's statute of limitations
If you have a documented monetary loss and the provider will not pay, small claims court can be faster than regulation. The filing limit varies by state.
Gather bills, receipts, screenshots and a written demand letter.
Send a final demand letter before filing; it often prompts a settlement.
Step three
Formal complaint letter template (US telecom). Copy it, fill in the bracketed fields and keep a dated copy.
Send it by a method you can prove — email with read receipt, or tracked post — and keep the reference number.
If it is not fixed
Use these routes only after the provider has had a fair chance to respond, or if they have breached a published deadline.
Questions
Call 1-800-288-2020, ask for a billing review and a complaint reference, then follow up in writing. If the charge is not resolved, file with your state public utility commission and the FCC.
It depends on your term agreement and whether the service failed to meet the promised terms. Ask for the early-termination calculation in writing before cancelling, and keep evidence of any unresolved service problem.
No. The FCC's informal complaint process forwards your complaint to the provider and requires a response, but it does not award money to individuals. For compensation, use the provider, your state PUC, small claims court or a consumer-protection agency.
State PUCs vary widely. Many accept consumer complaints, require the company to respond, and can investigate patterns of poor service or unlawful billing. They generally do not resolve private contract disputes or award damages.
No. The FCC forwards an informal complaint and requires a response, but it does not award money. For a refund, use the provider, your state commission or small claims court.
