Ordered prescription diet for my dog--then due to the long shipping lead times for prescription diet with no verification information on the Chewy website--I never uploaded the vet prescription. They shipped it anyway and charged me for it! Then it was lost in transit and NEVER received--they don't know where it is. This after they said I would receive it in a few days and could donate the food. The package went "poof" and disappeared. Called FedEx and they said that Chewy would have to call them and escalate. Called customer service again and they don't know where it the package is... I have 0 confidence in Chewy's customer service--they say they would make it right yet nothing was made right. I did get a credit back for the UNAUTHORIZED purchase at least. Would not depend on Chewy for critical prescription vet food and went with Petsmart who actually was able to complete the order.
