For one- outback reptiles is not the most trustworthy of breeders if I'm recalling right. Now then, this is just my personal opinion.. You purchased a snake knowing full well it had eating problems. Did you ever force feed? It may have saved your snake if you had.

Personally, if you didn't want the responsibility of force feeding, or the risk of it not eating and dieing- why buy the snake? You took the risk when you purchased his animal, and if he replaces it then it's him going above and beyond for your mistake.
