How can singularity be infinitely small?

When black hole is created, all the matter collapsed into infinitely small point with infinite density. But how is it possible, if the shortest possible length is the planck length? Does it mean that matter collapses into something smaller than planck length? If not, then the density can't be infinite. Since there is finite number of particles collapsed into something of planck length, you still can calculate density and it's not infinite. And if all the particles collapse into something shorter than planck length, then it's not the shortest possible length?
Where am I wrong?

This is not true. Black-hole formation is still an open problem. When a black hole is created, there is the formation of a classical horizon, but other than that, no one knows what happens, and if someone tells you otherwise, it's just pure speculation.
