Conteminated food

Hi I come to the restaurant on Wednesday the 16th, around lunch time with my partner as we usually does, I then ordered chicken prego with chips and salad...the only meal I eat on the day. At night I didn't sleep from stomach cramps, vomiting and diarrhea that lasted for 2 days, I almost died of food poisoning. I can't believe after I told the waitress that The chicken was off because of that awful curry marinade; she answered by saying that is how you make it. Me and my partner we been supporting the restaurant for close to a year now and this is the Thank you I get! I am so disappointed and disgusted!!!
