First of all, I already received the Transfer ID from the seller
And I thought I had completed the transfer, but it didn't apply
When I tried to apply it again, it said it was already registered
I asked through support, but they told me to prove the purchase, but I don't have a receipt because it was a used transaction
For me, the transfer ID and a few serial numbers that the seller gave me are all there is
Is mail through support the only way to solve it?
