Zevenwact mall spur rotten food

I went to spur in zevenwact mall cape town the one in kuilsriver. Had such a terrible experience.we ordered food I did not eat mine it was me my boyfriend and my sister and 3 of our kids. We ordered spur ribs with the chicken wings ,the wings had a terrible rotten taste since I didn't eat mine the same day I took it home as a takeway I ate 2 wings and realized that the chicken wings were off. My family woke up with a runny tummy I called the store the manager advised me that we need to firts go to a doctor while they are doing their investigations. Where must I get that money from for a doctor I mean I feel like I paid for my myself and family to get sick.
