Mad at my son's daycare.

Just went to the daycare to pick up my son and found out that they didn't feed him until 3:00pm. His morning feeding was 7:15am. He cought cold these several days. At 10:45am he threw up and fell to sleep after that. so he missed 11:00am's lunch time. He woke up at 1:00pm. They waited until 3:00pm snake time to feed him. I asked them why they didn't feed him right after he woke up. The answer is they have to do it according to scheduler. 1:00pm is not lunch time or snake time. So even though the baby missed the lunch he will not get fed until next feeding time. After he switched to the toddler's room from infant room two weeks ago I wasn't happy at all. He threw up every day last week even though he was not sick. My conclusion is he didn't get enough care. What should I do next? quit?
