Last time I tried something like this my rep didnt budge either

Use an excuse such as "Not long after eating It, I felt nauseous and ended up vomiting".

To take It one step further and spend an hour of your time by visiting your GP/Doctor. Explain your situation and get a medical certificate. When you support your claim to SkiptheDishes with a medical certificate, they must comply with OHS (Occupational Health & Safety) and given the nature of your experience after consuming their food, your SE will succeed.
