Maybe the community is more help than the support team ;)
So I responded to an order from a buyer. He contacted me needing some content written for his website. I accepted and we bantered over the details and reached a conclusion. A decent amount plus a tip if he was impressed. I was happy to get started so I gave him an offer and waited. Apparently, he had already accepted the order and talked like he had an active sale with me. I told I had received no order confirmation and he told me to "check again." Any seller knows you get live notifications about orders and I had nothing, but I went to the sales page anyway and took a screenshot for him.
Just before I sent that, I received a document from him apparently showing a bank invoice for a transaction in the correct amount with Fiverr. We both had our "proof" and we both agreed to bring this up with Fiverr support. I'm just glad he doesn't appear to blame me, and doesn't think I blame him. But I wanted to get the community's opinion on this problem.
