dollars for gold alliance precious metals ripped me off. took my gold, no check no contact vancouver, British Columbia

I found there website as one of the first via google search.  listed as seen on tv.  Sent my package (they provided tracking number which does not work) and have no received check. made several attempts to contact via phone but they don't answer their phone and you cannot leave a message. On their website you can "contact us" via a net based text message that comes back error page cannot display when I submit, but get an verification email saying they received my message and will contact within 24 hours.. sent about 6 of those last week, no word.  How can they get away with this?
