every picture of shed had a shelf included in it.

my husband put it all together only to discover there is not a shelf to put in the shed. 

i called and spoke with rep of wayfair. i thought it was missing. the 2 of us read together in
the instructions that the customer has to purchase a plank if he wants that shelf that's in every photo.
should we take it apart and ship back to wayfair?
not practical. should wayfair provide reimbursement for shelf. seems fair to me
please be in touch.
