Can you guys help me?? Adidas nmds

Hey so I need some help cuz idk if I got scammed off of kixify. Basically I bought adidas nmds off of kixify, the guy (username JPMATT) sent me the tracking number and all and according to kixify and usps, the package already went through the post office and are in transit to my destination. They were supposed to come yesterday, but there still not here, and they are apparently in transit since like December 4th. Just today, the guy's account on kixify dissapeared, saying it got disabled. Nothing came to me that my order got canceled or whatever, so idk if he could even be scamming me if my package is already on it's way to me. Can someone please help me and kind of say if you think I am being scammed or not, cuz idk what to do. I didnt know who else to ask so I came here. If you guys could put your input in, I would really appreciate it. Thanks
