25 Year Old

I had a beard transplant by longevita in Istanbul, turkey as it was quite expensive here in the USA. I wasn't quite happy with the procedure being carried out. They were very professional up until the point I paid all my money upfront. During the procedure they treated me like some kind of animal. Before, when I had sent them the pics of myself and how I would want a beard and mustashe they agreed that it could be done but when I arrived at their clinic they said a lot could not be done. For example my mustache was thin and I wanted a thicker one. They said that can't be done because the if they were to implant hair into close vicinity of the already present hair, the existing hair would fall out. And also that they couldn't plant anything below the chin as there are nerves there (which would be pretty much all over the face). So a disappointment when I had paid up. So the only thing that was done was the side of the beard was raised higher from both sides (that was literally it). So that was really just the review. Now my problem is, it's been six months and I shaved the beard from the sides slightly down to try and get a slight jawline beard but there seems to be a slight dark shade with the line up to where they tranplanted(so you can see a fake line). I have attached a photo to this review. Is there any way to get rid of this dark shade or will I have to live with this permanently?
