I would suggest you recheck your email cause most all orders are processed in 24 hours most within hours depending on time of day. If they sent you an email clarifying something on your order like say if you used a freemail email like your using here they might ask for a real email and the order will be on hold till they recieve a response. You may even have your details already who knows
There is no one you can call to cancel an order. All correspondence with customer service can be had by emailing
