Delivery drivers take clients for fools

The delivery driver call me at 13:58 to say he is in front of my gate. He does not introduce himself or anything. While he is calling I had to try and figure out who the hell he was. After figuring that out I immediately called my sister that is staying on the premises to go out to collect the parcel.

She call me back at 14:02 and reported that the driver already left.

I called him again at 14:03 where he responded saying he don't have time to deliver. He have a appointment at 14:00.

All this happened within 5 minutes.

The worst part is he called me at 13:58 the email saying that he couldn't make contact came thrue at 14:01.

That is 3 minutes whereby I had to decipher who he was because he couldn't even introduce himself properly.
