Newegg Refusing Delivery Help

So i ordered my build and it's coming from 3 different warehouses (i got 3 emails stating the item list being shipped from different locations). 2 items are coming from TN, 1 item from somewhere, and the rest of my items from CA

In one of the item lists, i had selected a motherboard which I no longer want now because a lot of people are having problems with it. The motherboard is grouped with the rest of the items from CA.

My question is.. Is the motherboard + all the other parts coming in one gigantic box or will it be in multiple individual boxes.

If it's in one gigantic box, how am I supposed to refuse the package to return it? Do i have to ship it back...

usually they all come in one box and you will have to ship it back yourself

I talked to them and they said i can just refuse the delivery if i don't want any of it. I'll just buy the build sometime in december. thanks anyways
