When you understand the intricacies of foreign corporations and international banking institutions, you might no longer have your mind blown.
Then you may realise why everyone else uses payment protection, rather than having their mind blown, when a large foreign corporation, loses track of an international banking transaction. And you may be encouraged to do the same.
I do hope you get your money back. But it could be a long road.
Without being rude, can I explain why Paypal works so well. Paypal don't actually give the seller your money. They hold your money, and guarantee to give it to the seller when you receive your goods. In a case like this. Amflow agreeing to give you a refund, would have seen Paypal immediately return your funds, as Paypal was holding your money, not Amflow, and multiple intermediary banking institutions.
