Had the same kind of situation happened on us for few times already. Usually the first time resulting in "Not Granted, We successfully defended the chargeback." or "Granted, You are not responsible for this chargeback or its reimbursement."

But then a month later, suddenly one day the chargeback reappeared, without asking us or giving us the opportunity to "represent", but status become "You are responsible for this chargeback, and you funded the buyer reimbursement."

Asked seller support, they just kicked the ball to chargeback team, and there will be ZERO response by chargeback-billing-reply at amazon either for sure from any appeal.

Obviously Amazon accounting not approving to cover up those payments, so why not took it from seller when in the past Amazon's favorite response would be "Card issuer had re-disputed the chargeback and we are unable to defend it".

Who knows if chargeback team "really" attempted to defend or what's the story behind? Isn't it the whole process is only visible to Amazon's side, not seller?

Amazon CEO is in need to bump up sales revenue and margin by each quarter, in order to lift up the company's stock price and not disappointing the shareholders & market. Amazon doesn't care why sellers are losing money, no matter it was their policy loophole which enabled buyers to scam easily or not. Because at the end, when one seller was dead, another one will be replaced, and same on repeatedly, meaning Amazon continued to collect large amount of referrals fees off marketplace sales. Take a look at Amazon's earnings reports to have better understanding how marketplace sellers made up a great portion of profit to Amazon business. If Amazon managements are "really" listening to voice of sellers, 70% of policies need to be updated in order to shut down loopholes.

This should be what Amazon had said from the beginning about "Losing money is part of doing a business".
