Worst service ever!

On 21 December 2020, my son posted a parcel to me, from Los Angeles, USA. It came as speed post from there, with a tracking number! It has never arrived and there is been no acknowledgement from SA Post Office of any correspondence. I have been to the local post office 15x times, I have emailed the international division on 5x occassions, with no reply other than an automated promise that they would reply within 24-48 hours. Every time I go to the post office I get a different story. No one will come back to me and no one will take the responsibility for finding anything out. There is no hope for our postal system. However you can order anything online and it gets to you in less than 7 days. Its just pathetic!
