Missing luggage: Greyhound porter lost my bag and no one wants to account even with CCTV footage

On Saturday , 01/12/2018 ,13:00 , I was supposed to board a bus from CPT to Klerksdorp , by the time I got to the bus terminus in CPT we received a message stating that the bus will be late, an inconvenience I accepted.

Before the bus i was waiting for could arrive , I asked one of the porters what time exactly will the bus be here and he just said it will be late and I left it like that. when the bus arrived, I approach the same porter, who happened to be the closest Greyhound representative I could ask a question to, and asked him if the bus that had just arrived is the bus I was looking for , and he confirmed it was, he went on to offer to take my bag to the bags compartment as I go on to do the boarding procedure as the bus was already late and I gave him without suspecting any malicious intent. The potter took my bag and by the time I arrived at my destination the driver and I realize my bag was not loaded onto the bus we were on at the least, which was surprising because he was the same person that showed me my bus.

The driver went on to contact someone at the bus terminus to inquire about the lost bag, and whoever was on the other side confirmed the description of my bag (sky blue adidas sport bag with lime stripes and trimmings), but it seemed not to have a tag according them(really?), although it did have a tag ( I have the half to show for it) and said I can either get it from the bus that comes to klerksdorp in the early morning (i.e. approximately 05:00 am , ) or I can choose to collect from the bus that arrives later on at 10:50 am @ 03/12/2018 (as an exact time i was given), and I chose this option. At this point it is important to note that they have admitted to having my bag and even offered a time slot and arrangement to get it to me.

Today I go to the agreed collection point ,on time and that bus was late also by approx ( 40 mins) , the driver of that bus knew nothing about the bag and was kind enough to go through the bags with me, after it was confirmed that the bag was not there, the driver tried to get hold of CPT through Johannes (operations manager) but he didn't know anything, told me he will look for my bag ( which was supposed to be in their possession by that point) and I should just be patient as he works on it , in the meantime I should allow the bus to leave. He took my contact details and kept quite from that point .

I followed up by trying to contact the customer care services and from that point I was sent from corner to post , waiting a minimum of 3min 50 seconds with every call I made, just to be told " we can't help you call lost and found" , I do as instructed and lost and found says " call CPT and ask because I can't help you from JHB " , I call CPT , got passed around and made to wait until I was given a number which apparently will be answered by Abby who will know what to say to me because the person that answered was admin staff, Abby never answered.

I called Lost and found again and I was told to explain, I did and the lady there tried to call CPT herself and she couldn't get through. I eventually got Johannes again , and he did confirm that Abby checked the CCTV footage and that they could see me giving the potter the bag and the potter did not put it in the bus ( where is it ? nobody knows) , and at this point : remember they first agreed to having it and made arrangements first for me to collect, arrangements failed and now nobody knows where my bag is, and all I am getting is a no one taking responsibility for the potters actions, instead Johnnes tried to turn it on me saying it was my responsibility to make sure my bag is loaded (really?) , then what is his job ?

So it seems nobody will agree to take action or responsibility, they are living me with no option but to consider both civil and ******** lawsuit , because I really did have valuable items in that bag and medication , that has since slowed down my life.
