Review Bad experience

Good day, Yesterday I went to teriyaki boy here at Mall of asia Branch together with my fellows. After they took my order they deliver it on specific time that hasnt match to what they said serving time.Then the food came without serving cutleries and waiting to long for a server to came in and ask for it. Then they served the drinks late without straws and pointing for a small spoon to used as alternative.When the server "Ramon" served the food he introduced by a shorcut named I dont understand maybe their type of naming the food by themselves but not so formal.When I got a bite of California rolls, I noticed a flies on my food that loss my appetite I Informed the server about the food and they change it right away without even APOLOGIZING, not even a manager on duty to check back. As they delivered the new California maki still no apologized for the server nor manager. And when about to eat it again theres still flies on it. So Ive got my phone and started recording the flies on my food that goes on all of our food too. We loss our appetite. I ate a food that i knew contaminated. I ask for a bill and a manager to speak with me. When we are talking about the food Ian the manager on duty saw the flies roaving around as I pointed and says "see?". Its a shame on the store as the server and host was look like weak and sad for entertaining customer , poor management and very bad experienced for my last day in Philippines. Hope this will be a Good Call for everyone.
