Because Whoosh orders are immediately sent to store and dispatched via delivery partners, it is not possible to change or cancel the order through the website or app once you have checked out. If the order is already on its way – refuse the delivery when the driver arrives so It can be cancelled and returned to the Store. Individual products cannot be returned to the driver at the point of delivery. Non-perishables should be taken back to a Tesco store for a refund. If you are unhappy with any of the products, please contact Tesco Customer Services.
