Good evening, so I´ve got the following problem, I have a customer who ordered a "Midterm Destruction" box. I sent it out to him and 3 other customers, now the problem is: The others got theirs but his Package is always being send back to me. We checked the adress, I reshipped it and it cost me money for 2 shipments. Now the second time they couldn´t deliver it either and try it again tomorrow. What can I do? Should i open a ticket or just wait and what about the shipping costs?
