A withdrawal of consent by a party does not affect the legal effectiveness, validity, or enforceability of a notice or document delivered by electronic means to the party before the withdrawal of consent is effective. A withdrawal of consent by a party is effective within a reasonable period of time after receipt of the withdrawal by the insurer. If an insurer fails to comply with § 58-1-30, the party may treat the failure as a withdrawal of consent for purposes of §§ 58-1-27 to 58-1-39, inclusive.
