I highly doubt the argument itself was relevant whatsoever.
Maybe I need to find a different bank?
Nor should you quite frankly. Kids buying stupid things is not the same as fraud.
$500 for items stolen off my porch. So they WERE delivered, but I didn't receive the item.
Over $1,000 for a hotel I booked and they wouldn't let me reduce my 5 day reservation by 1 day (the first day because I realized I couldn't get there on the expected day). I went back and forth between the booking website and the hotel 3 times each with them both telling me only the other could change the dates. So, I charged back the whole stay and found a different hotel for my updated timeline.
(Also, a bit of a side-point: The chargeback notices always had a VERY short window during which you were allowed to contest them. In most cases we had about 5 days to respond, but sometimes the notice wasn't delivered until after the respond-by date.)
I have the opposite experience with Mastercard. Of the dozen or so disputes across 5 cards I had over the years I essentially lost them all. Visa is somewhere in the middle. They tend to side with customer but also will investigate thoroughly.
