Fnb ebucks buggy Kauai voucher

Trying to use the ebucks benefits is really difficult if the Kauai voucher is not refreshing. The voucher stays redeemed and no agent. All confused about the issue. The voucher was there every month and then stopped. I did not use the voucher much, but when needed it was there. I met all qualifing criteria. It has now been about 4 months. I go stand in queue to order and does not work. Now i have waist time with FNB chat to explain everytime. Most frustrating time.
