Good evening,
I am Luciano De Castris from Italy, for the first time in many years a dispute has been opened against me by a collector from Algeria who says he did not receive the registered letter with the stamps and is asking for a refund. I have the images from the Italian post office with the tracking that proves that the registered letter arrived in Algeria, and if it disappeared it happened in Algeria. I refused the refund and wanted to know what to do.
Thank you
regards
Luciano
