Unhygienic Food

I have been to Food*****s Boksburg regularly for personal purchases as well as big corporate purchases. I've had a few issues and whenever addressed as a client I was never made to feel a priority. Yesterday I purchased a vegetarian meal, No 1 the item on the slip vs what I purchased doesn't tie up. No.2 I am having lunch just after returning from my purchases and have something rather chewy in my mouth aind I tried to understand what could this be, when I removed this from my mouth it was an elastic band, this is absolutely disgusting, a minor difference if I had found it in my plate but I chewed onto this. This is a huge health issue and I demand answers and how I would be compensated failing which I will take this matter further, cos I'm tired of Food*****s Boksburg treating me as a number when all clients are valuable. I have since yesterday called a few times and reach an automated system saying the voicemail is full. I couldn't get the email address on the voicemail and used the one on the till slip. I'm still waiting for a response, I also provided my mobile number to be contacted and sent pictures, no response yet.
