Security Breach

Hi
I posted last Wednesday about your email link sent to a client that opens someone else's invoice. 

Since I received no reply to the email I sent you about how to proceed and what measures you were taking, I have now contacted the people involved with the leaked invoice. 
I thought it appropriate that they knew. 
could someone look at my email and tell me how they would like to proceed with the private information that's was leaked? 
thanking you
