Camperos Grill and Bar

My family ate there on Sunday, 2-16-2020 at noon. We had the buffet. The food was already cold, we were one of the first groups there. Three of us got sick; the doctor stated I have food poisoning. We called the restaurant to notify them, but they did not believe us. We were told nothing would be changed in the way food is handled unless we all submitted our confidential health records. We asked for the manager to call us back since 2-17-2020. We have called several times to notify the manager to hopefully prevent others from getting sick, missing work and having to pay for doctor bills and medications. No one has returned our calls or is willing to listen to the complaint. We are not asking for a refund nor any type of compensation.
