Final Notification issued after parcel sent back.

I have waited patiently for my parcel from overseas for longer than the expected delivery date, when finally I received a 2nd and final notification at once that I need to pick up the parcel within 21 days. Both notifications were delivered on Sunday and it was already 2 days over 21 days that is allocated for pickup. So on Monday the post office informed me that my parcel was sent back. Please note that I never received a FIRST NOTIFICATION, and only a 2nd and FINAL notification on the same day, and only after my parcel was already sent back.<br> <br> Now we cannot find the parcel. Your call centre and JHB International Mail Centre don't answer any calls and after holding the line for a while my calls keep being dropped. This happened over the course of a couple of weeks.<br> <br> I know I need to pay an outstanding amount for import tax as per the notifications, however it does my head in that I cannot get hold of someone to track down this parcel and send it back to my postal office so I can pick it up.<br> <br> This was bought as gift and I am so frustrated with SAPO.
