Wrong labeling-Protea Glen Mall

Hello,I purchased a Margharita Pizza Slice (R39.99) from your Protea Glen Mall store for my daughter. The label says “Margharita,” which should only contain cheese and tomato. However, when I got home and cut the slice, I discovered tuna/fish inside. She's allergic to fish I have photos, packaging, and price label as proof.

I can't access their website

Thank you
