Aramex Couriers — Delays in delivery, Lack of information

Address:

Nizwa, Hay Thurath, flat 2

I have been using Aramex for some time now and there have always been problems with delivery to Nizwa, Oman where I live.
The couriers are unresponsive and unreliable. Customer service is impossible to reach. They only provide a chat box which doesn't even answer sometimes. The couriers are sometimes rude.
My last delivery has been sitting in Muscat for days now and no one has updated me.
