TOTALLY ROBBERY！if i could give negative 5 – Instacart-Get Grocery Delivery Review

The delivery guy changed my order totally by adding incredible amount for I want to have. I thought he did swiped the shelves to add in my order. Plus, I did not receive my order at all. Should I call it a ROBBERY？Totally unacceptable! I would never ever use this app any how! Cannot explain the high rating. Does the developer delete any bad comments or bad ratings？
