After receiving a notice from an obligor as provided in section 1666(a) of this title, a creditor or his agent may not directly or indirectly threaten to report to any person adversely on the obligor’s credit rating or credit standing because of the obligor’s failure to pay the amount indicated by the obligor under section 1666(a)(2) of this title, and such amount may not be reported as delinquent to any third party until the creditor has met the requirements of section 1666 of this title and has allowed the obligor the same number of days (not less than ten) thereafter to make payment as is provided under the credit agreement with the obligor for the payment of undisputed amounts.
