If the seller sold him as enchi to you and misrepresented the animal maybe you should give him a call about your dissatisfaction. Ask him if there is some way he can make the situation right. See where that takes you and if you are not satisfied go to plan B. Most breeders will stand by their productions if they value their customers and their reputations. A word to the wise is sufficient. Good luck.
Just got off the phone with him now actually. He is 100% sure that it is an enchi so yeah. I like to give people benefit of the doubt but yeah, this enchi looks nothing like the ones I've seen on the internet.
