It shall be an unlawful practice for a sponsor to sell or offer for sale pay-per-call services that involve provision of value-added information, not product sales, with a supplemental tangible item sent free of charge to the customer after the completion of the call unless all advertisements and promotions for such services include:
(1) an 800 number or business name and full address for callers to obtain additional information or to follow up on items not yet received; and
(2) the true market value of the item to be sent free of charge and a complete and accurate description of the item.
