Those are all of the steps that we took back in October and our IT team spent days to confirm all of this was done and accurate. And no, nothing in my junk/spam or anything else. 

There is no accountability from that point on. It's like "oh well, sorry" and it's dropped. There HAS TO BE MORE THAN ONE TYPE OF NOTIFICATION for business owners if email isn't reliable. We have LOST over $20,000 in the past six months because we aren't receiving ANY emails on these chargebacks and disputes. Needless to say we have customers with free products, services, equipment. This is a LOT of money to be out for a small business owner. 

It's very obvious that Quickbooks is a massive enough sized company that it doesn't care if it loses a few customers because of things like this. All you get is lip service. "I am so sorry this happened" "Oh sorry there isn't anything else we can do". "Oh I totally understand, sorry".
