Worse delivery service in South Africa

Yesterday UPS "attempted" delivery by hooting at the front gate and ringing the bell. The bell is not for my townhouse, and I cannot hear the hooting at the front. So I phoned them yesterday to please give me a call when they are at the gate. The guy that was helping me phoned operations to make a note. So today I was home again, no delivery. When I checked, UPS "attempted" delivery once again by hooting and ringing the bell which I told them will not work. The lady say the couriers carry personal phones and I have to phone tomorrow morning to make the arrangement. So their incompetence and delivery problems is mine. No one is just interested in assisting. I don't even know why Amazon make use of them. None of the other courier services have this problems.
