Fact is, this breeder is doing a very good job with post-purchase customer service. It is winter, and if you did as much research as you said you did, you would know that winter almost always means no shipping. It is just too cold for ectotherms.
Have you provided proof to the breeder that the snake is indeed dead?
We all feel for you and know this isnt an ideal situation, but the fact that several people, myself included have asked what "Quarantine" means to you...and you give us the run of the mill correct definition, and not whatever you did for "quarantine" when you brought your snake home. What exactly did you do to/around your snake in what you called your "quarantine"?
It does sound like you know what you are doing with husbandry, I am just not convinced that the breeder is at fault here.
I still smell fish.
