(3) For listings obtainable from records used by the directory assistance operator, upon notification to the company of the error, mistake or omission in such records by the customer, the company shall be allowed a period of three business days for the correction to be effected. If the company has not corrected the error, mistake or omission within three business days after notification by the customer, credit shall be given at the rate of 2/30 of the basic monthly rate for the line or lines in question for each day thereafter that the records remain uncorrected.

The terms shall refer to addresses only to the extent that an error, mistake or omission of an address places the customer on an incorrect street or in an incorrect community.
6. (6) Such allowances or credits as specified in paragraphs (1)-(3) of this subdivision, shall be given upon notice to the company by the customer that such error, mistake or omission has occurred; provided, however, that when it is administratively feasible for the company to have knowledge of such error, mistake or omission, the company shall give credit without the requirement of notification by the customers.
