I have placed and received a supplementary order and according to the accompanying invoice, my Previous Balance was unsettled. Why is this? As far as I know, I have already settled my latest balance.

Answer:

The unsettled balance in your account may relate to your coming standing order delivery. Invoices are printed in good time before we start packing since they also serve as packing lists. Standing order products are packed manually. The amount payable is the amount that relates to your supplementary order.
