Ordered an item from the on the weekend. after ordering it I notice it was not the correct specs however not able to cancel order online so called then on 9am Monday morning as they are not open on weekends advised that she had locked the order and I would get an email to say when it had been cancelled yet I got an email saying it had been shipped after they was closed. Waste of time don't bother very poor customer service.
