AQ394136997CN was delivered in Canada on May 12.

I hope you purchased the goods from a big online marketplace like ebay, Amazon, aliexpress etc. If the item is purchased from a website which has no contact name, no company address and no phone number, it is very likely to be a scam. The reason is as following:

The tracking number A****CN is called China Post direct mail which can not be tracked in your local post system, so you can't know where and whom the parcel was delivered.

Many cheaters extremely love to use such A***CN parcel to cheat buyer. Their typical game is to sell some high value goods with extremely cheap price and ship some garbage to destination city(but not buyer's address). Then they tell paypal that they have delivered the goods to buyer and get money from paypal. So buyer normally feel quite difficult to claim money back. To make things worse, these cheaters might sell your credit card and personal information to other criminals.
Please try to open dispute to paypal against fraud. If paypal has records of many other buyer complaint, you will easily get refund.
Never buy from such scam websites or sellers.
