Yep that's shady for sure, sorry to hear you didn't actually get the frogs you were after. I personally don't think if the store selling the animal doesn't even know how to tell the difference between species they shouldn't be selling them, to me that's a clear indicator they don't know what they are doing and how to give the animals the proper care they need till someone buys them. I was in a pet shop here a couple days ago just looking around killing some time and I came across a terrarium were they had the animal inside labeled as a Pacman Treefrog, it was a pacman but we all know those chunkers aren't climbing through trees. I just laughed and looked at my daughter and said I would never buy any animal from the store.
