should you be at rank 70 or above and still missing Warbonds to unlock the last items.
If all goes well, you should have enough Warbonds to unlock every item (that can be unlocked through Warbonds) when you rank up to 70.
In case you don't, please take some time and thoroughly check your loadout and note the exact number of Warbonds you are missing.
Then reach out to an EA Advisor - explain the situation, tell them how many Warbonds you're missing. They won''t be able to grant them straight away but will pass that on to the relevant department, so please allow some time for this to be handled.
