Regrettably mistakes can occasionally happen.
If you think you have been refunded the wrong amount please contact us by logging into your account and raising a support ticket, quoting your order number and the required refund amount.
Delivery charges are non refundable (unless you have received a wrong or faulty item from us or you send back the entire order) so you will be refunded the full value of the items returned less the delivery charge.
If a discount was applied to your original order, the amount refunded will be adjusted to allow for the revised order value and appropriate discount level.
If you still cannot find the answer to your question please contact us by logging into your account and raising a support ticket.
