Buyer did not agree to cancel the item

Buyer did not agree to cancel the item !! After sending wants to cancellation the purchase.
I told him must agree to cancel until it 
But he did not do! What I do 

Thank you dear, but this is a long-time item not sold
This stupidity and not fair, the buyer did not pay the requested cancel the purchase, then go no return
It did not listen to the seller
