it's been 3 times in the month that our customers are debited 2 times in a row for a single transaction. Payment takes place in the iframe of paypal integral evolution. A single basket and a single order on our website and at paypal 2 transactions 10 minutes apart. No upstream transaction control with the basket number which is nevertheless part of the data sent to paypal. And there surprise, I manifested with customer service so that paypal reimburses our client and reimburses us the commissions otherwise it means that we pay twice the commissions. Once on an official transaction and the second time on a transaction that must be refunded and which is not our fault! What does customer service do? Above all, no action on their part, no reimbursement, we are told that we can reimburse but that we will have to pay the commissions above (and then what else ??) and who otherwise must appeal to the incompetence of their merchant technical service which spend almost 3 months intervening on a basic problem which only depends on paypal, dozens of emails exchanged, hours lost for nothing, only do everything to demonstrate that paypal is not responsible and that therefore they can neither help us nor reimburse us the commissions on the transactions debited in excess by their system !! So we are the ones who pay for their mistakes. The policy of thieves, liars and incompetent, unable to have telephone support up to the problem solving.
