My bank sided with the merchant, because the merchant said "Tracking number shows it was delivered." Which has nothing to due with my item (less than 80grams) not being in it's box.

It's not hard to use common sense, of which your bank has obviously failed to exercise. 

Did you explain to your bank that their decision based on the tracking details, Is totally Irrelevant to your claim?

I even asked my bank what was the weight bestbuy provided for the shipment, and they responded "They didnt provide that information"

My goodness.

Is It that difficult to check the records on the carrier's manifest and get the consignment weight? I do It everyday at work In literally 60 seconds. Tell your bank to do their job and get the details as requested.

Yeah I told them that what they were claiming has nothing to do with my claim, but all they kept saying was "Well Best Buy said." I will dispute again, and maybe this time the person doing it wont be a complete idiot.
