Ryback is about decimating his opponent. His opponent in this case is CM Punk and not the referee so his objective is to get CM Punk, it's clear that he's after retribution and he's getting closer to it while looking like the dominant guy. Ryback doesn't need to complain as he's about destroying, eating and dominating his opponents - just like John Cena said he's not about winning the Championship but about destroying someone. The referee got annihilated by Ryback at HITC, so I guess they made up for that there and then instead of continuing the storyline with the referee. Ryback isn't going to complain but he's going to leave it in the ring.
