The order (which was 20 min late) was for Brownie Blast krusher, instead the delivery guy said that they only had Choco Lash, the unavailability of which wasn't informed by phone, email, or any other means.
Upon finishing the krusher, I noticed a thin strip of plastic moving along the walls of the plastic cup (a picture of which is enclosed here, with is kept on the rim of the plastic cup).
It may seem like something small but it could be potentially dangerous, and should not be present in any food.
Bill also attached.
