no help from sapo

I am waiting on several parcels from overseas. According to the tracking info provided by the merchant a parcel arrived at the South African airport on the 7 March 2015. Since mid April 2015 I've been trying to get help from the South African post office as to the location of my parcels. I have contacted the call center, wrote an email and continually phoned Cape Mail and the Johannesburg International mail centre, all of these avenues yielded no results. The email I sent over three weeks ago to the customer service email address, with no response up till now, and nobody answers the phones at JIMC. How can it take close to three months for a parcel to reach Cape Town from Jhb? <br> The processes available to aid customers fall far short of the mark.
