> Not sure if you guys ever received calls claiming that they were DHL/FedEx etc, and there was a package for you to pick up. More ridiculously, sometimes they even claim to be the Chinese Embassy and of course there was package for you to pick up.

Can you elaborate? this happened to my partner and we thought it was something targeted at Chinese foreigners. They were persistent and it was kind of worrying because my partner accidentally gave up a small bit of information before catching on that it was not legit. Are they trying to do identity fraud?
