Making a change to any listing will put it back at the top of the
searches for a short time. Letting your listing collect virtual dust on
eBay will make it fade away.
If you want to avoid the frustration of the reps just go the Facebook
Ebay for Business page and message them. They will get back to you
within a few hours and are very helpful. Just make sure it's the vetted
page with the blue circle and check mark.
