This could also be from fraud. Card testing for example, where they aim to figure out missing card details. Or some other nefarious use of stolen card details.
But this is a slightly different story. With chargebacks, almost every time it was just a customer not wanting to admit fault. What’s strange is that they could have simply written to us and asked for a refund. But I guess they realized they were in the wrong, so instead of contacting us, they went straight to their bank.
I’ve been a credit card user for 30 years, and in the first 25 of those years, I only had to resort to chargeback once. In the most recent 5 years, I’ve had to do it about 3 times. Companies in general are just way less responsive now and take their customers for granted way more than in the past.
