Here is so far what I found out about the situation. I hope this might be helping you.
One of the LV representative told me that I can talk to UPS about this matter directly. However, I was not able to talk to them with customer service number, and I called to the local UPS office where I dropped off the package.
Apparently, LV opened a claim to UPS when LV reported the package was delivered as damage to UPS, UPS started the investigation. The first thing they did was to try to pick up the damaged package since it's damaged, not missing. LV failed to provide the damaged package with 3 attempts. That's why the UPS claim was closed because there was nothing to investigate since LV didn't provide anything. This description matches that I have read from the tracking detail after they opened the claim. I called LV again after I talked to UPS people and the representative was not answering my question about where the box is now and if they can provide the box for the UPS investigation this time for sure, and she hung upon me. I called them again and trying to confirm if they can actually show any effort to make this claim working with me and I am getting even more angry about their attitude towards to me.
I also had a call with arbitrator, and she said because of the price of the bag, this is not worth to pursue and she advised me to look for small claim court. I haven't done much of research of it yet, and I am still trying to get in touch with LV but once again, this is the worst in my life time shopping experience.
