Delayed baggage

Terrible! My baggage was left Schipol. I flew KLM from AMS to JNB. No baggage was loaded. I have been trying for 2 days to get hold of SOMEONE or ANYONE to give me feedback on status of my bag.....cannot get hold of ANYONE!!! Literally on the call waiting for someone to pick up the call. After 45min of waiting, I gave up. This happened on MULTIPLE occasions! Still no feedback or response! I have no idea where my luggage is. Terrible!!
