Utility Company Billing Dispute Email That Got Me $400 Credit

PG&E overcharged me for 6 months before I noticed. Here is the email that got me a $400 credit. Subject: Billing Error Resolution Request - Account #[Number]. First, state the specific billing periods and the amounts you were charged versus what you should have been charged. Include screenshots of your bills and meter readings if available. Second, reference your state's public utilities commission regulations. Just mentioning them signals that you know your rights. Third, propose a specific resolution: "I request a credit of $[Amount] to my account reflecting the overcharge for the period of [Dates]." Fourth, set a timeline: "Please respond within 10 business days. If this is not resolved, I will file a complaint with the [State] Public Utilities Commission." Utility companies respond faster to written disputes than phone calls because written disputes create official records.
