I'm having the same problem with you
waited the whole day with my condo front door open, no one came, no one called, no slip of paper
suddenly dare say addressee not available
had one experience where i was not home with DHL, courier called me, i didn't answer. put slip of paper, then i make request re-deliver again, the next day courier called me if i am at home, then done finish no problemo
that is a good service, this? this is annoying, blaming the recipient not being home when i was at home the whole day just to wait for the courier to come
