now what

Call customer service, they should attempt to make it right.
(Don't send it back for a refund unless they plan on FULLY refunding you, don't let them subtract a BS restocking or shipping fee either.)
If not?
If you paid by credit card, call your CC company, and file a complaint.
I had to call Visa, who credited my account $1700 and they reached out to the lousy business, in this case a moving company that tried fleecing me.. If the business doesn't fight them on the payment, case closed, you were just reimbursed.
