More questions about CanvasDiscount

We have a PO Box as they do not deliver mail in this area. UPS and FedEx do deliver, as far as our billing address its associated with all of our bil They sent me an email say it is ready to be shipped, but haven't sent me the tracking number even though it has shipped. What do I need to do? I received confirmation that my order is ready to be shipped awhile ago and I have yet to receive an email that says it has been shipped. Where is my order and why won't you answer my emails? I also tried calling you and kept getting hung up on because you are too busy to answer calls. Will I receive before Christmas? Does CanvasDiscount customer service have a phone number that a customer can call to talk about their dissatisfaction with an order recently received? how can i tell if my pictures will be blurry where will the prints be shipped from? If I place an order now, how long will it take for the canvas to get to me in Virginia? i have a credit I wanted to use .Yet I don't know how to send the picture I want to be printed...can you help me with this?..thank you
