what do you do when the zipper gets caught?

I cant believe anyone would do that and then try to sell the bag on ebay saying that the bag is in "very good condition". But then again, I cant believe anyone would actually bid on the poor bag.
 
I really don't understand why you would do that, usually a caught zipper can be worked free. If a zipper got caught on my Chanel and I couldn't fix it I would just leave it caught. Those small pockets aren't that useful anyway.
 
If (IF) it had a security tag on the inside and the bag was stolen, the only way to remove the tag without having the ink pack explode would be to cut it out.

I think that is a stolen bag.
