Got a couple of plastic/glass shardes in a cup cake I ate. How can one confront such a situation? I dont have any proof! We have one more pack of cup cake left from them.

Was bought from a bakery in Thalayolaparambu. They make it themselves I think.

This is approx 1.2 cm x 4mm x 0.5mm. Feels more like plastic than glass, not sure. Had one more smaller(around 5mm) flat piece, but lost it.
