Yes, this is a problem and so many merchants are getting their accounts and funds locked up by being unable to fight these friendly fraud disputes that have been taken advantage of by the consumer.
This sort of fraud hurts both the consumer and mostly the merchant as the bank which doesn't know any of the context of the payment takes 3 seconds to see the dispute and 98% of the time, the merchant loses and the bank forcibly takes the money away and gives it back to the customer, especially for digital subscriptions. Instead the consumer should contact the merchant directly to resolve the dispute.
At least VISA knows it is a problem. What is Mastercard doing about this?
