Yes, many of us are incredibly responsive to customer support inquiries (I have a <1hr response time unless you send in a ticket when I'm sleeping) and it doesn't matter. Fraudsters gonna fraud. This isn't a case of "they asked for a refund, we refused, they issued a chargeback", it's a case of a scammer being a POS.
I've dealt with my fair share of chargebacks and in every case I've seen it's someone being a jerk and never a legit case.
The fact that Stripe won't help you, the banks don't care about all the evidence you have, and you end up out the money for the product _and_ you get hit with a chargeback fee on top of it is madness. I could literally have video of the person holding up their ID saying "I XXXXX agree to pay YYYY" and banks would still side with a the scummy scammers.
I have, quite literally, never had someone reach out via support and then file a chargeback later. They do it without reaching out, probably because they are a trash person and they have no interest in getting anything fixed and are just scammers.
