I received an email from Japan Post stating that a parcel could not be delivered due to an incorrect address.

It says that I have to pay a 42566 yen fee and submit my correct address as soon as possible in order to receive the parcel.

It's obviously spam!! They can't have my personal email address. However, I was initially unsure because I received a phone call from Singapore Post confirming my address yesterday. Was that call also spam?!

Recently I receive many spam calls from unfamiliar numbers originating from the US, Thailand, Saudi Arabia, and other places almost every day.

I usually ignore those calls, but sometimes I accidentally answer those calls. Then I speak to them in Japanese, pretending that I don't understand English at all. Most of the time they hang up the call immediately.
