Why do I get an error message telling me to contact my bank when I try to use my Woolworths voucher in store?

When using Woolworths' vouchers on purchases over $5, please ensure that you’re using the ‘eGift card split payment’ option if you are paying at a self-service checkout counter. If you select any other option you will receive an error. For in store checkout, Woolworths' staff should also put the vouchers through using this method of payment.

Please also ensure that you are using vouchers with a positive remaining balance value.
