@Nataliesgramma I realize this can be frustrating, especially if you really want something and more importantly, by a specific date. What you posted is common practice with the Q, whether we like it or not, and whether we think it is right or wrong.
When I order from QVC I rarely go back and check the status, it is what it is. Maybe once a week or so, I may check on something but I pretty much let it go. Also, I've learned to never order from QVC if I need something quickly. Most of what I order is a "want" and not a "need". I've also seen where an item is as you described, processing and/or backordered, and then lo and behold it is delivered.
To avoid frustration maybe not check the status multiple times a day. It could drive you nuts.
