Query: Customer support non-existent

I ordered this item for my 2002 Ford Ranger Edge. Great price on Goldbox.The instructional dvd would NOT play. It was scratched.After opening, I realized I needed some extra items from bulldog to make this item work with my vehicle.I emailed them numerous times, and left them numerous voice mails. They never emailed or called back.I am sure this item works for some people, but I don't trust a company that can't back up their product by providing support.
