I once paid extra on aliexpress for quick shipping and had the same experience. I got a shady text message demanding money or my package would be destroyed. I never responded because I assumed it was fake. So eventually the courrier shows up at my door and says I owe custom fees which literally cost the same amount as what I paid for the item! It seems that you are more likely to get nailed for customs and duty if you pay for the faster shipping which is insane.
