I'm a new seller. How do I handle it when a buyer doesn't pay for an order? Does hipstamp automatically notify them or do I need to tell hipstamp about this. It's been 2 weeks for one buyer. And I did email them but no response. I saw on here that I can cancel the order but if I do that frequently HipStamp could penalize me. That doesn't seem fair if it's not my fault. Any help is appreciated.
