Just the same as if normal matter falls in. The matter or antimatter will stay there, increasing the mass of the black hole (and making it more "hungry", i.e., making its gravity stronger).
Objects which approach a black hole will get sucked into it.
Your life will be over in an instant
The matter gets crushed as tiny as it can get.
They get destroyed. Their matter becomes part of the black hole.

This happens in the beginning of Wizards of Waverly Place the Movie. Alex gets sucked in as well.
In a black hole, all matter and energy that crosses the event horizon gets sucked in due to the immense gravitational pull. This includes light, particles, and even information, which becomes trapped within the black hole's singularity at the center.
