If the consumer's authorization is oral, the motor vehicle repair facility
shall make, on both the written estimate or firm price quotation and the
invoice, a notation of the
name of the person authorizing the repairs, the date, the time, and the
telephone number called, if any. Any charge for parts or labor in excess of
the original estimate must be separately authorized by the consumer as
provided in subsection (b) of Section 15 and in Section 25.
