If you notify us of any charges on your bill you claim are unauthorized, we will investigate. If there are charges on your bill for calls made after the Device was lost or stolen, but before you reported it to us, notify us of the disputed charges and we will investigate. You may submit documents, statements and other information to show any charges were not authorized. We will advise you of the result of our investigation within 30 days. If you do not agree with the outcome, you may file a complaint with the California Public Utilities Commission and you may have other legal rights. While an investigation is underway, you do not have to pay any charges you dispute or associated late charges, and we will not send the disputed amount to collection or file an adverse credit report about it.
