Hulk Volume Discount Bundles

The app is completely misleading. I set up a promotion so my customers will save 10% for 1 item, 20% for 2 items, 30% for 3+ items...as the app suggests they can do. I paid for advertising and posted the offer on all my sales channels and social media. Only to get a heap of complaints that it only works if they purchase multiples of the same item. Who wants more than 1 of the same thing?!
When I contacted support, they took hours to get back to me and fobbed off my issue saying "sorry we don't support this function". I've had to refund customers the difference, take down all my advertising and re-advertise at my own cost, as well as losing customers trust. Their marketing is completely misleading and the support is non existent.
