Any breeder with 15 years experiance, and selling 180 morphs at a show will have known beyond a shadow of a doubt that THAT was not a mojave.
Would you hand someone a apple and declare it was a potato chip? That's how exceptionally different a mojave is from a normal to a EXPERIANCED breeder, which YOU said this person was, by your "15 years, 180 morphs, nice folks" stuff.
That person sold you a normal as a mojave, overcharging you, ON PURPOSE. That is not a mistake, anymore than I'd accidentally hand over a cat to someone who gave me money to buy a toaster. If you like getting scammed, that's your own business, but this site is unusally devoted to making sure that new folks DON"T get scammed by unscruplious sellers.
