I Pre-Ordered an Iphone 17- stolen in transit given an empty box

I preordered the iphone 17 pro max on Sept. 12th, I was looking forward to getting it today. Fedex brought it to my house, I signed for it and thought it feels really light, I brought the box inside and noticed it was packed with brown packing tape, but the tape had been torn and over the top of it someone placed clear packing tape to reseal the box. I thought immediately of the stories I heard about ppl stealing GPU's and putting bricks inside the boxes, I opened it up and the seen the seals on the iphone box were torn off, phone was removed, charging cable left inside the box. 

I contacted xfinity support and they said they would issue a refund, and I had to place a brand-new order and go to the back of the line so no phone until the end of October. I found out later talking to another customer service rep that the refund wouldn't be issued until an investigation was complete, anyone know how long that process takes or what it entails? The agent told me I would get $400 off promotion on the new order that was placed, then I was told later by another agent that there was no such promotion given. I saved the transcript of the agent telling me I would get $400 off, not that it will make much difference I guess.

I have the ring camera footage of the fedex driver handing me the package and you can kind of see the clear tape on top of the brown tape, I asked the agent in chat if they wanted the video and was told maybe at a later time, they would want the video or pictures of the box.
