I would definitely ask the seller immediately and take the snake to a vet. The photos aren’t in focus, but it looks like those might be wounds or burns of some kind. A deformity is possible, it’s hard to tell without an exam. It will be important to have an experienced herp vet document their exam findings, diagnostics, and any treatment. A cat/dog vet isn’t sufficient. I can confirm, I’m a retired dog/cat vet. 
Good luck!
