If your matter is not resolved by working with our Customer Service Department, you may forward your issue to the CPUC, send the bill and a letter stating the basis for the dispute to the following address:
California Public Utilities Commission's Consumer Affairs Branch
505 Van Ness Avenue Room 2003
San Francisco, CA 94102
(800) 649-7570
If the disputed amount is still due, please follow these instructions. Please enclose the disputed amount, made payable to the California Public Utilities Commission. Upon receipt of the payment and your letter of dispute, the Commission will review the basis of the dispute and disburse the payment accordingly. The Commission will not, however, accept payments if your dispute appears to be over matters that do not relate to the accuracy of the bill. Examples of issues the CPUC would not assist with include water quality, low pressure or hours of operation.
