As I read this I can see this would be upsetting, however, you provided little detail, so I reserve judgement until more information is provided;

How long have you had this 500?
Was it new when you purchased it, or refurb?
What did Axiom tell you about the warranty?

Having purchased my first Axiom products in the late 1980's, and needing some support over the years, I think Axiom has excellent customer service.
