The vast majority of affiliate reps that I have had contact with have been very helpful and friendly. They don't always have ther answers or tools I request but they have usually been helpful and polite. A couple of new/small sites with little to no marketing materials even offered access to members area and said I could create my own banners and galleries if I wanted.

A few sites that I really wanted to promote on my amateur blog never wrote back or simply gave 2-3 word e-mails telling me to screw off (like the response you received). I don't really have the time to deal with it so I put them on a list of contacted and no.
