Hi @Anonymous User
If the vouchers electronically embedded on your Stick haven't uploaded onto your account (check My Passes on here, just in case towards the top of the screen page there is a message saying " Vouchers Waiting For You" with a link to redeem.
Then if there is no sign of these vouchers, jump over to live chat for further assistance & help where this issue has been reported by a lot of customers over the last six to eight months.
Use the green chat button in this link page below.
