Paid the Same Utility Bill Twice? Use This Refund-vs-Credit Test
If you paid the same utility bill twice, confirm whether both payments posted to the same utility account. Leave the extra payment as a credit when the next bill is coming soon and the amount is manageable. Request a refund when the account is closing, the duplicate amount is large, the credit will not be used soon, or the payment created a separate bank/card problem. Do not assume a universal refund timeline or policy; check your own utility account, payment confirmations, and state regulator or complaint path if the utility will not resolve it.
