I recently moved to a new apartment. When I went back to the old apartment to try to get my mail, I was shocked to find out that they had returned all my mail to the postman. I asked the security guy where should I go to collect my mail and he said "moo nie jai", which is as good as I don't know.

Any idea how I could get my mail? I am expecting some important letters.

Go to the post office that serve your district and ask the postman. I hope they haven't returned them all to your senders. Good luck.
