SA post office. Incompetence or ignorance maybe typical 3rd world.

I posted a parcel to Germany 14th February 2022 at 11:32:08. I have had absolutely no feedback . Called post office, told to call Cape mail, Debbie at Cape mail tells me that my parcel has been in customs since 17th February 2022.,said that she would follow up and get back to me,asks for my phone number, that was on Monday 28th February. Today- I called because she hasn't called back yet and she tells me that my parcel is still in customs. She says that she couldn't call me because she couldn't call cellphone numbers and says that she had told me that ,certainly not the truth because she took my number without any complaints.. I asked her to enquire why my package hasn't been posted to which she replies that there's nothing that she can do about it . So I have paid for speed Services that doesn't work,and on top of that apparently there's no solution for the problem. What a sorry state of affairs..service and service delivery minus zero. Shocking and disgusting to say the least, how backward can you be in this day and age of technology and Internet. Do they really don't care or are they seriously not capable of running a postal service system. Where do I go from here. Can someone please help me.
