I would take it to the dealer and complain. They should drain your oil and refill it manually counting how much is in there.... (free oil change).
I got a free oil change due to my dealer screwing up when my oil was slightly low one time. The put less than half a quart in and it read over full, but since no one knows how much over full is they were forced to drain the oil and manually measure it. Turned out to be just a couple ounces over. But they had to refill it with fresh oil
