hi team :smile:

im getting the above error code when trying to redeem the code in the Epic launcher.
it also says: THIS CODE CAN ONLY BE USED FOR ACCOUNTS IN THE SPECIFIED COUNTRY. PLEASE USE ANOTHER CODE, OR CONTACT OUR CUSTOMER SUPPORT.

Im in New Zealand and play on pc.

ive already contacted Epic and they said to contact 2k which ive also done with no reply so far
