Panda Express review: food angus meat

I need to make a complain Yesterday August 8 we dine in at panda Express. We notice the Angus taste different so we asked one of the employees was there something different about it. She said no everything still the same a d smiled and walked away. So today my kids husband and I haven't felt good we started burping the Angus meat and throwing up. Something needs to be done about this. Yes if prove needs to be shown that we were there I have my cc transaction because I wasn't given a receipt. This place was my favorite but not any longer I will never go there again.
