Billing Questions and Appeals

  • Billing Questions and Appeals

    If you believe your bill is incorrect, call our customer service line at 800-700-2443 before the final service date printed on the bill. We will promptly investigate and advise you of the results. In the event the dispute is not resolved, we will inform you of the complaint procedures of the appropriate regulatory authority.

    Natural gas service will not be disconnected for the bill you are disputing but subsequent months must be paid while the bill is being investigated. You will not be required to pay the disputed portion of your bill that exceeds the average usage for the billing period at current rates.

    If you have a serious health problem that will result in someone residing at your residence becoming seriously ill or more seriously ill if service is discontinued, we may be able to continue your service for an additional 20 days. We must receive a written request from you or a written statement from a licensed physician no later than five working days after the due date of the bill. Our customer service representatives can work with you to provide a deferred payment agreement. Customers 60 years or older may request a payment extension of up to 10 days past the due date without penalty.
