Poor Handling of a Complaint

I am on a SAMTRAC training course from 08MAR to 19 MAR. On the first day during the induction, the facilitator indicated to us that if the food is bad we should not complain to him. He doesnt care. He mentioned that we didnt pay for a meal and got SAMTRAC free. From the Monday up to Thursday the quality of the food was poor. 7 of the 9 persons agreed. 2 of us decided to complain because the \no complaint policy should have been told to us up front. There are persons whose quote include a cost for meals which they have paid. On Thursday the meal was bad. The rice was boiled to almost a porridge state. The food was dry. A male by the name of Elandre van Zyl (who I am told is the training co-ordinator) went to investigate. He was very RUDE. He told us had spoken to the facilitor and we were there for the SAMTRAC and not the food. He didnt see anything wrong with the food. Are we not allowed to complain about poor quality? Because of his rudeness, My job entails coordinating training and surveys. I will recommend to my employers not to use NOSA again. We are a big Company with almost 2000 employees country wide. Elandre van Zyl does not know how to handle customer complaints."
