Con-artist, *****ster or too wise?

Eugene is nowhere to be found. We have been fighting to get around R30k from him since 2015! He promised to deliver a service which he never delivered on. He eventually sent me a letter of admission of debt and promised to pay me back. He had a different excuse every time I asked him about it and eventually changed his number, address and stopped answering my calla and messages. Proper con-artist. He operated under different company names since I first approached him for help!
