I have purchased stuff from same seller nearly 20 times last year and all came within 10 days.. this time it's 7 days and no update on tracking number

I am worried as the stuff's cost is more than 500USD

there can be 2 things

1. The Seller is Trying to Scam.
2. HongKong post didn't scanned the package yet in their systems.

So can anybody help me ?
