Triple Dave's Burger Illness - Wendy's, Thornton Colorado

1500 East 104th Avenue, Thornton, 80233 Colorado, United States

Three of us ate at 3:49 pm at this location. It was my sister and a friend). We all had the Dave’s double hamburger. We all started with vomiting or diarrhea within 35-40 minutes after we ate.
I’ve tried calling the restaurant since 4:30 pm yesterday and the line is busy. I called their Customer Service and they said a District Manager will call me back in 10 days. My sister is in a care facility. | Symptoms: Diarrhea, Vomiting
