Please feel free to Google 'Reviews on Aramex in South Africa'. You will find that this must be the business with the most bad reviews ever. Read those reviews and you will see exactly how many people have lost both their money and their goods that were entrusted to these people.
My wife and I sent a parcel within Durban municipal borders, and with a wave of the Aramex wand, it simply disappeared. They allege that they have delivered the parcel (to the wrong person), and when you ask for proof of delivery, they simply ignore you.
It seems we are not the only ones to whom this happened. In fact, the sheer number of similar complaints points to nothing more than a scam. If I was a detective investigating these guys, I would suspect them of criminal conduct. It's a pity our own SAPS is such a lame duck, as these guys deserve to be investigated.
