Is Mr Christo van Heerden threatening his clients?

Mr Christo van Rensburg told my son in an e-mail today that we can pick up the Ford at lunch to-morrow...... lets see if it will happen. It seems to me that Mr van Rensburg only found out today that I was telling my story on public media as he send my son a whattsapp to tell me that I am playing with fire. I wonder if he is threatening me?
