  Let $\mathbb{G}$ be the quantum automorphism group of a finite dimensional
C*-algebra $(B,\psi)$ and $\Gamma$ a discrete group. We want to compute the
fusion rules of $\widehat{\Gamma}\wr_* \mathbb{G}$. First of all, we will
revise the representation theory of $\mathbb{G}$ and, in particular, we will
describe the spaces of intertwiners by using noncrossing partitions. It will
allow us to find the fusion rules of the free wreath product in the general
case of a state $\psi$. We will also prove the simplicity of the reduced
C*-algebra, when $\psi$ is a trace, as well as the Haagerup property of
$L^\infty(\widehat{\Gamma}\wr_* \mathbb{G})$, when $\Gamma$ is moreover finite.
