A customer bought a software I had written. Within 15 minutes he immediately started to complaints. He/she claims that the documentation is not available, which is actually provided. Before that, 21 people bought it. I helped many of them.
Still, I could refund the money.
But she/he shared my source code in the comment area.
Speaks slang, irreverent, patronizing on me and terrorizes the comments area of the product.
This is a first for me. What should I do?
