(a) Delivery of the repaired or purchased item must be made by the date promised or stated for delivery in the written estimate, unless the consumer is notified of the delay and the new anticipated completion date in writing or by oral communication supplemented within one day by a writing. If complete repair is going to be delayed more than ten days the consumer must be informed of his or her right to request the immediate return of the property, completely reassembled.
(b) In the event that the consumer chooses to exercise this right, the dealer must immediately initiate and carry to completion whatever steps are necessary to secure the return of the consumer's product, and may charge the consumer only for work specified on the written estimate which was authorized and actually completed prior to the requested return of the product. Any deposit paid by the consumer in excess of what the dealer is entitled to receive, as described above, shall be returned immediately to the consumer.
