Cancelation of transaction denied

[Anonymous]

Hi ,

Buyer wants to cancel a transaction after not replying to my emails for a while with some weak excuse that he already had the item. I just don't believe a thing of it. I told him that I don't agree to cancel and want him to pay. Now I'm worried that when he receives the item which is in perfect order he is going to lie about its's working or condition and open a dispute to get his money back. Anyone experience with this matter or advise? Thank you. I just lost a lot of money to a dishonest person claiming he didn't receive an item while I had proof of postage. So I am extra worried. Thank you.

kind regards, H
