My tattoo artist messed up my tattoo and I don't know what to do?

Well you SHOULD have seen it before you left and before he put it on you, BUT he did **** up. You brought it in the way you wanted and he ****** up, and of course no one thinks that the tattooist will **** up a tattoo especially if you brought it in the way you wanted it. What you should do is call them, tell them and see if they will give you money back or try and fix it, if not don't go back there and until it heals wait. When it does heal go to another tattooist try to see if they can work with it, if not then get it removed off.
