Most store purchases are not permanent account unlocks unless the product specifically says so. Consumables and delivered items are one-time purchases and last until they are used, lost, destroyed, wiped, or otherwise removed through normal gameplay.
VIP is permanent, but individual items such as supply drops, weapons, vehicles, deployables, or placed objects may not be permanent unless stated on the product page. If you believe a purchased item should have survived a wipe or was lost due to a delivery issue, submit a help ticket with the order number and server.
