How to File a Complaint Against Duke Energy
Step 1: Contact the Correct Regional Customer Service Team
Begin by contacting the Duke Energy utility that serves your account.
Use the regional number shown on your bill or in the official Duke Energy contact information.
Step 2: Explain the Problem Clearly
Provide your account number, service address, dates, billing amounts, outage information, meter details, or other information relevant to the complaint.
Explain the resolution you are requesting.
Step 3: Request a Supervisor
If the first representative cannot resolve the issue, ask for a supervisor or higher-level review.
Record the representative’s name and any case or reference number.
Step 4: Provide Supporting Documentation
Keep bills, payment confirmations, meter photographs, outage records, emails, screenshots, notices, and other documents related to the complaint.
Documentation is especially important in billing and service disputes.
Step 5: Request a Billing or Meter Review
If you dispute energy usage, meter readings, charges, or billing calculations, ask the appropriate utility to review your account.
The company may have procedures for meter investigations or billing corrections depending on the issue.
Step 6: Ask About Payment Assistance When Appropriate
Customers experiencing financial hardship should ask about available payment arrangements, assistance programs, and qualifying nonprofit resources.
Available programs vary by state.
Step 7: Escalate the Complaint Through Duke Energy
If the issue remains unresolved, request review by the appropriate billing, customer-service, operations, or regulatory-affairs team.
Provide details of all previous contacts.
Step 8: Contact Duke Energy Corporate Headquarters When Appropriate
For a serious unresolved corporate matter, correspondence can be sent to:
Duke Energy Corporation
525 South Tryon Street
Charlotte, NC 28202
Routine billing issues should normally stay within the appropriate regulated utility escalation process.
Step 9: File a Complaint With Your State Utility Regulator
If a regulated utility complaint remains unresolved, customers may contact the public utility commission or public service commission in their state.
These agencies oversee regulated electric and natural gas utilities.
Step 10: Keep Complete Records
Document all calls, account notes, complaint numbers, bills, emails, and written correspondence.
Keep records of any promised adjustments or follow-up dates.
Step 11: Contact an Appropriate External Authority
Depending on the nature of the complaint, additional consumer-protection or government agencies may have jurisdiction.
For utility-rate, service, disconnection, and billing disputes, the state utility regulator is generally the most relevant outside authority.
