Complaint Review: Dining Advantage

I just got a customer in my restaurant with a coupon from this app. My restaurant's management has not signed up for anything related to Dining Advantage or had even heard of this until today. I decided to look into it in their app and website, and there is my restaurant listed with "coupons" that DO NOT EXIST. Did some digging on their website and found that the only way to contact them is through a website form (no support/customer service number). Found this suspicious and looked into their LLC name (HSP EPI Aquisition LLC). Found that they had the name of entertainment.com with a lot of fraudulent reports and comments!!! It consists of buying the coupons/sales
