The written notice shall identify the contract, state the names of the extender of credit and the consumer, and shall include the date and a reasonable description of the violation.
In any case where the extender of credit must respond in writing to a complaining consumer, the written notice or other required written response shall be mailed to the last address contained in the extender of credit's file on that consumer, unless the consumer specifies a different address in his written notice sent to the extender of credit.
