Slow delivery, no feedback, no answer at call center

I've been asked to send through proof-of-payment for an online purchase for the purposes of customs clearance to Tiro. I have done so 2 days ago. My package has had no status update. There has been no feedback from anyone at Aramex despite emailing several people. Aramex South Africa is incredibly slow compared to using Aramex in other countries. I would at least expect a reply from one of the 7 people contacted within 24 hours.
