Triceratops Rigged 3D model Low-poly 3D model

Dears, I was really looking forward to use this model for a short film I'm producing and even found a 3D guy to help me put it in. I was surprised and highly dissapointed by the project I bought. Here's a list of the main issues with this project : 1 - Eyes - The 3D model of the eyes are behind the texture of the main body model making them invisible when the main texture is applied. 2 - Beak - The beak isn't properly placed on the model, there's a gap between the face and the beak. 3 - Rig - Claws - The claws are not connected properly to the rig of the feet. When you move a foot, the claws stay on the floor. 4 - Rig - Back Legs - When you move the legs after a few centimeters the bend then break totally. 5 - Horns Texture - The textures are bad or simply badly placed. My guy couldn't figure out a way to have them show properly. By default, the texture model is visible on the horns like there are straight lines when the texture finishes and starts again.

Here, it's not the case. I'm very dissapointed by my first purchase on this website.
