Contact problem regrding a problem

Hi, I have recently purchased and paid for an Adobe product that I haven't got. And I can't get a reply from Adobe to my inquiry. All very disappopinting. Can anyone advise me how to get a reply re my purchase (but non supply) of Photoshop Elements. I understood this to be a major reputable company. All it seem to do is ask me to purchase it again. Any suggestion appreciated, Robert in Oz. Thanks.
