Query: DO NOT BUY PRODUCTS FROM PACIFIC DIGITAL!!!

I BOUGHT A PACIFIC DIGITAL EXTERNAL CD BURNER FROM AN INTERNET SELLER. IT CAME BRAND NEW IN A SEALED BOX WITH ALL THE WARRANTY CARDS AND EVERYTHING. I AM HAVING TROUBLE INSTALLING IT SO I CALLED PACIFIC DIGITAL SEVERAL TIMES FOR HELP ONLY TO GET VOICEMAIL. MY EMAILS WERE NEVER ANSWERED EITHER. WHEN I FINALLY GOT THROUGH THEY TOLD ME I COULDN'T GET SUPPORT BECAUSE I BOUGHT IT FROM AN "UNAUTHORIZED SELLER!!THAT IS UNCONSCIONABLE!!! THIS COMPANY WILL BE OUT OF BUSINESS SOON BECAUSE THEY DO NOT STAND BY WHAT THEY SELL.
