I've had a couple packages delivered to me that were clearly ripped open and then taped back up. Of course the jewelry in the box was gone.
If I'm returning a piece that costs more than $100 I use QVC's return lable but I still go to the post office to ask for a receipt to prove I mailed it back. It cost nothing to do this and I highly recommend everyone do this just in case. It should be done with every piece, even if it only cost $20 and you're paying the return shipping instead of paying their label and the $6.95.
Things can happen. I was sent a Barbara Bixby empty box. I had never ordered one of her pieces so when I contacted CS I told them I could send a picture of the empty box and they could check to see that I had never bought one of her pieces.
I've gotten packages that are ripped and the box and item are still in there when they could have easily fallen out.
I received a ring one time that I did not order. Of course I sent it back.
Like I said, things can happen. I had a few things happen when QVC had gold day. Maybe because I ordered several pieces and so did a lot of other people. The Judith Ripka earrings I ordered never came so I called CS about a week after it showed they had been delivered. They were very nice and sent me a new pair and put a trace on the ones I never got.
Sorry my message is so long. I know it's upsetting when things like this happen. Insurance is included when we pay shipping. QVC did tell you that the otems were missing. They use paper packaging so it's kind of easy to open the package. I always staple my packages when I return them. So along the way someone could have opened the package and put a piece of tape on to close it. Have you asked them if tape was used?
I've found that QVC and HSN both have really good customer service. Keep in contact with them and ask about tape or staples if you didn't use these to reclose your packages.
