Did not recieve my entire order

My package arrived with half of my order missing... when I reached out to customer support they said I still had one more package that should be arriving soon... This confused me because the invoice in my email says that all of my items were delivered and even gave me the option to review the items that I haven't recieve yet (Which is what I'm doing now)... customer support did provide a tracking number for the remainder of my order but when I try to track it there is no delivery info available. I'm not sure why my order was supposedly split up into multiple packages and shipped out on seperate dates but i have my fingers crossed in hopes that I will actually recieve it soon and that it's not marked as 'delivered' somewhere in their system... The half of my order that actually did arrive was exceptional as always.
