Who do I contact about a refund or return for a purchase that is not under an Instalment Plan?

You need to discuss refunds for returned products directly with the merchant you purchased the product from, since they will process the refund.

^Up to 110 days interest free on humm90 Mastercard purchases (excluding cash advances) when you meet the Interest Free Criteria. You must pay at least the ‘Alternative amount to avoid interest’ on each monthly statement, by the statement due date. Any outstanding balance after the Interest Free Period reverts to the humm90 Purchase Rate.
