I haven't been asked to sign for any delivery from any retailer for more than about 18 years. That was for a computer setup costing thousands of dollars, not so unusual at the time.
OP- no idea where your package is, but I hope the man who accepted it for you is an honest person because no matter what QVC does now, it will take time.
I did once have a package delivered to the wrong address - QVC took care of my problem, but it did not happen in 2 days and it wasn't Christmas time.
