I recently had logos made at fiverr. After the seller sent me the logos, he went missing in action. It's as if he took down his profile and went dark. So I contacted customer service to let them know that I could not find my seller, and that he has not sent me the source file (which I paid extra for).
My transaction was automatically marked as complete- even though the seller did not send me source file. I complained to customer service, and they told me that transactions are automatically marked completed in 3 days, whether or not they are actually complete. So, reaching out to customer service to tell them your order is incomplete is not enough proof that your order is incomplete. You have to press the freaking button within 3 days. Waste of time and money. Should have stuck to eLance.
