BOLD Discounts ‑ Flash Sales

I had used this app for a few years, then during Cyber Monday 2025 I changed some sales prices and it changed some and made others a higher discount. I deleted all of the current sales and then even the app entirely, but THE SALES ARE STUCK ON MY PRODUCTS even without the app installed. Tried customer service which was not open. A week later and still no reply from customer service. This app cost me thousands of dollars. DO NOT INSTALL!
