I doubt DHL would tell you about any incoming packages for security reasons. Especially given how people's packages get stolen from their porch when its left outside. Such service would make it so much easier as thieves will know what day to wait around, and where.
That's strange. I never had problems with that.
Just calling DHL and asking if I have anything coming just because of that same reason.
They ask you for name/post code/door number etc and say if there is anything coming...
I like DHL... Fedex & UPS is pain the ***
