@DarlenerayI don't think you're getting the runaround, although I know you're not getting the answer you want.
I think the items are missing because the bag is a return and whoever returned it kept the dustbag and registration card or even the even more valuable add-ons QVC sometimes includes. Same thing happens when we buy off the sale tables in brick and mortar, but we see what's missing before we buy and can decide whether the lower price makes up for the reason the bag is an "as is" Sometimes my answer is yes, sometimes it's no.
Life is pretty strange sometimes - we want to keep the past we like and change the past we wish were different. Wake me up when that happens!
