Call up any lawyer in your area charging less than $200/hour, explain your situation in less than 15 minutes, say that you are willing to pay him/her $100 just to send that competitor a formal letter demanding them to stop the redirection or threaten further legal action. This sometimes works, i.e., assuming your competitor is not well funded enough to afford a lawyer either. Otherwise? I don't know, do something similar to your competitor?
