Inconsistent Information Regarding Promo Code Validity

Request #***0: Agent ShaunD. Inconsistent Information Regarding Promo Code Validity. I am disappointment with the inconsistent information provided by ShaunD customer service agents. Initially, the agent informed me that the code was not valid. However, after further discussion, the same agent stated that I needed to refresh my cart, and the code would be applicable. I find this inconsistency troubling, as it wasted my time and caused frustration.
