Shocking SA Post Office

I cannot seem to understand why an international parcel arrives in the country in January and the information is captured on the SAPO database on 14 February 2019. Thereafter nothing happens. My parcel has not moved from the JIMC since 14/02/2019 which is extremely shocking. I also have another parcel which has been in transit from JHB to CPT for a month now. Surely it does not take a month to travel from JHB to CPT. The customer service contact number rings and rings. I have asked to officially lay a complaint but no one has bothered to provide me with the email address to forward my complaint. What's worse is I don't want to relive the instance where my parcel was delivered a year and a half later! This is completely unacceptable!!
