Email is the preferred channel for order documentation because it allows us to review attachments and keep a written record of the request. Response timing may vary with weekends, holidays, order volume, and the complexity of the request.

Order and delivery support

We can help clarify order confirmation details, address correction requests submitted before dispatch, tracking information when available, delivery delays, and parcels that appear lost. We cannot guarantee that an address can be changed after dispatch, so check your address carefully before submitting payment.

Returns and product concerns

Do not mail a return before receiving written instructions. Our Return & Refund Policy explains the request window, hygiene restrictions, evidence for damaged items, return shipping responsibility, and refund timing.
