Bad Tattoo

I had a cover up done 2 years ago that was ok, but not great. I didn't like the lettering, coloring around the tattoo and how one of the flowers were. I went to an artist named Catra and talked to her about what I wanted. I wasn't looking for a cover up again, other than the lettering, the stem of a flower, and some bits of coloring around the tattoo. Problem is she really botched it. She covered over things she shouldn't have, and didn't do what she drew out on my arm. What we agreed on was one thing, and I got quite another. It looks more awful then when I walked in. Question is, does anyone know of a really good artist in the lower mainland who can fix bad cover ups, and is willing to touch someone else's work? I would do laser, but the shops owner hasn't returned my emails regarding my complaint/concerns... and I shouldn't have to pay thousands of dollars on my own to remove it. I got jacked around badly. And this is no small piece, nor will it be easy to fix. It needs to be an artist with a lot of experience, creativity and who specializes in cover ups. Thanks.
