No refund, no replacement

DVDMD.TV sent me damaged discs when I first ordered.  Then asked me to mail them back at my own expense so that I could get a refund or replacement.  I did so and they stopped answering my e-mails.  I called thier help line (which has since been disconnected) multiple times and each time they assured me that my replacement was on it's way.  I have never recieved a replacement or a refund and am still being ignored by the company.
