Losing NX when Inventory is full!

Hey. WL_ here.
I can't login into my other Forum-Account and can't reset the password (No Email recieved), but that's another Story.

About 2 hours ago I bought 3 Cash Equipments.

1. Head Bandage 4.500NX
2. Neon Amulet 1.300NX
3. Seal Pillow 4.600

After leaving the Cash-Shop I noticed that my inventory was full and I didn't recieve the Items.
I checked the Cash-Shop again, but they weren't there aswell and the NX was already gone.
Is there a way to get the NX or the items back?
Thankfully I started streaming before entering the Cash-Shop.
