ZZ Reroll review for ROCKET Sales Pop Up & FOMO

Been using this app for at least 5 years.... Today, suddenly this damn app bug out and make a $100 discount code to one of my customer. The customer basically get a free $100 worh of product for paying nothing. To make it worse, when I raised the concern the support team treat me like an idiot that do not know how to navigate the app. Hey, I have been using this app for 5 years, I know how the discount work, how to navigate those BASIC thing. Your app caused me to lost $100 and you know throw the blame on me?
