GDex / GD Express review: Delivery man

This afternoon I received a call from GDex and said they already arrived at guard house. I also already at guard house, but I didn't see any GDex truck. After questioning then only realized they were at another house of mine which is just one junction far away. Then I told them I will arrive in within 1 minute. Please wait. Then the deliveryman answered in a very bad tone said we can't wait, we still have many items to deliver as today is only half day, then he hanged up the call, I call back him immediately， he didn't answer my call, I continue call him.11.59 am, he answered my call. And said he is going to which place to deliver the parcel, if I am going to collect my parcel, please be fast (in a bad tone). After got my parcel, I questioned him, And he doesn't even apologize for this incident which I found is not an appropriate service manner should be. And 019-217 7073 is the deliveryman ， Please take note and won't happen again in the future.
