If a business attempts to steal from me I instantly charge back and the onus is on them to prove that I owe them money. I do this all the time and have never been blacklisted.
With some of the large companies, blacklisted is a real concern.
eBay is one known example.
I've heard the same for Amazon (forget if it was retail or AWS).
It's cheaper to lose your business than to have a proper human review every complaint.
I have a few customers like that. They sign up, forget about it, then they see it on their statement and issue a chargeback. Not only do they get their $20 back (that they very willingly signed up for), but I have to pay another $35 to Stripe for the privilege of having a forgetful customer who couldn't even be bothered to email me for a refund.
Yeah that kind of seems like antiquated fear-mongering. Next they should call the BBB and leave a strongly-worded review!
I don't think it's helpful to think about this as the company "trying to steal from you". There is no intention here. It's just something that got lost in a bad IT system. You gain nothing from issuing a chargeback. You imperceptibly nudge some statistic and a "banned for life" flag might automatically get flipped in a database. There's no righteous comeuppance here.
You try to contact support, pester them a bit, call someone if possible, and eventually, you may get your money back. If you don't, then you issue the chargeback.
Some companies like Activision clearly state in their terms that chargeback means you will be permanently banned, no exceptions. You'll lose your account and access to all digital "purchases" forever.
They don't need to prove anything to stop doing business with you.
