I want to tell a story about a buyer on Fiverr which ordered a 7 dollar logo. She filled the requirements, I replied to her related to her requirements, she confirmed me they are ok. I had a custom offer at a low price, for which I specified there is only 1 concept and 3 revisions. I implemented her the concept, and she returned telling me that I completely misunderstood the requirements and she asked for a new revision, which in fact was a new concept developed. Since this is a miscommunication problem from the buyer, and I also replied to her to confirm the requirements, why am I at fault here?
Is there a real difference on Fiverr regarding revisions and new concepts? The buyer started threatening me and asked for a full refund
