McDonald's sucks
You have to contact walmart directly.
Nobody on Google would know
Call the store or if you have time go to the store and speak to customer service. If it isn't available ask to see what is and if you find something you like have what you paid for bed 1 put towards your 2nd option. If there is nothing in stock be certain to have a backup option by shopping other stores. You will definitely have better luck finding something in stock at say a Bob's Discount Furniture. Or another similar Furniture store
Contact Walmart directly
My opinion is your ordered bed may be held up on one of the freighters stuck in the harbor. My suggestion, get your money back and order where it is in stock.
Contact the Walmart you ordered it from.
