Caesarean scar revision so much worse than it looked before

I had a caesarean scar done by Dr. Shim Ching done in Qotaina clinic , Kuwait 6 yrs ago . The outcome was extremely disappointing and very unattractive to look at . I very regret doing it with him . At first I thought an American doctor coming from Hawaii he should be really excellent , but unfortunately he made my scar so much worse than it looked before. I even hate looking at my stomach and it makes me feel so depressed.
