Beary Nice NZ review for Discount Master ‑ Quantity

I installed the app but to test it I had to agree to be billed for it so I installed it approved billing tried a code it didnt work for what i needed and promptly uninstalled it the same day yet they charged me for it because of this. They refuse to refund me because I tested a code on it. Pathetic and not good business. Dont install.
