I want to talk to you about this character and I advise you to leave him alone on any sales. This person,in addition to immediately claiming a discount on minerals, he also questioned their authenticity, a shame for him that my material always comes from 100% certain sources.  
I had warned him that given the Covid period, shipments abroad with certain countries suffer major delays. He still wanted the expedition, which was done. After not even a few weeks he pretended to get the money back via paypal complaint, too bad that the registered letter has stopped in the Netherlands since November 24 and he never deigned to ask for information on why it was not delivered, so for the Italian Post Office the registered letter has been delivered and therefore he must understand why he has not received it yet. Now the character is having fun slandering me in some social groups, he blocked private messages on facebook, which is what I did now as I don't want to know about this character anymore, and he hasn't written the whole story, showing himself as if he had been scammed. It will be my responsibility to notify paypal of his behavior, as well as the fact that in 20 years of sales one of my packages has never been lost and he would be the only case.
