DSW review: Pricing issue

Visited the Fair lakes, VA store (4/17/2025) to take advantage of the BOGO 50% offer. This offer clearly states in promotional material that upon purchase of one pair of shoes, another purchased pair would be offered at a 50% discount.
My issue:
The 1st purchase - A "Green" clearance item at $84.98, qualifying for 40%
The 2nd purchase - A display item at $79.99, qualifying for 50% BOGO discount
The clerk, along with the manager, completes the transaction by applying the 50% discount against the already reduced (less 40%) "1st" purchase instead of the 2nd, resulting in a higher overall customer price. The on-site manager summarily dismissed my complaint with significant irritation just for asking for review.
The published promotional material clearly refers to a discounted "2nd pair" with no stipulation as to the 1st pair: i.e. clearance items not stated to be excluded. The impact seems significant over the thousands of stores and customers.
