How can I agree to cancel a transaction after I have refused the offer. Seller's Paypal is not working.

I declined the sellers offer to cancel transaction because it was made without any explanation.  Because the seller is having a problem with his Paypal account I must now agree to the cancellation but I don't know how to proceed.  Please help.
