HRH Equestrian review for ADU: Automatic Discounts

I installed the app on Nov 21 and after trying to set it up and even messaging the support team, I was told what I wanted to do was not possible. Uninstalled it on Nov 24 - with 3-day-free-trial period, and to my big surprise, got charged for it on my Shopify bill this morning. I just emailed support - I hope they reimburse me. This is an extra charge I was not planning in this Covid/Christmas time when every cent is important.
