They are definitely the worst delivery company I only used in the whole world: I lost two days on them while waiting for an important package at home. The first time the courier came, didn't knock, didn't call, and left. The second day he just didn't show up but made a note as if he was trying to deliver a package. Customer service just covers the drivers: they keep saying, like parrots, "Sorry, sorry", promising to help, but in reality, nothing happens.
