Misrepresentation

Purchased shoes online, webpage states: All items carry a delivery fee of R75.00 incl. VAT. Free shipping on all orders over R450. Kindly note that any promotions on free delivery apply to the once off delivery only and not returns or exchanges. https://grendha.co.za/shipping-info/

I still paid for delivery, 3 emails later & they still won't refund my delivery fee.
