To be honest, I’ve never personally filed a chargeback, so I don’t really know how difficult the process actually is ))
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.
