I agree with whoever advised cancel and relist.
If you are not around to post items, it's a good idea to cancel listings or, at the very least, put your sales on 'time away' to avoid further issues.
"There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true.”
Søren Kierkegaard, Danish philosopher (1813 - 1855)
