I think this one is a bit difficult, because it depends on how big the business was. Technically you can say ...
-There is no way I will do business with him again (Ich mache mit ihm keine Geschäfte mehr). Although to me this sentence feels like there was a lot of money involved and maybe even a bigger contract.
When it is just a small shop where you were treated unfriendly I would say ... -I won't visit this shop again (In dieses Geschäft gehe ich nie wieder). -They won't see me again (Die sehen mich nie wieder).
@Nicole_1989 vielen Dank fuer die Antworten! Ich suchte etwas mehr in die Richtung von, “das ist keine Weise, Geschaeft zu machen”, zum Beispiel wenn du den Ladenbesitzer beschimpfen willst. Aber ich weiss nicht ob das genau richtig klingt....
