Poor Customer Service

I have been trying to get in contact with these people concerning why the program is not opening up when selected. I have emailed the AVCHD converter support, got 2 responses, 1)Would you please tell me where did you get this app? and what happened when you click on this app?, after I replied 2)Would you please tell us which version is your OS? , after i replied, I HAVE NOT HEARD BACK FROM THEM SINCE!
