LOSS OF LUGGAGE

Boarded a bus from P.E to DURBAN on the 20th of july 2015. On arrival to Durban, found that my bag got lost somehow during the trip to durban. When trying to inquire about the loss of luggage, the bus drivers were not that much interested to assist. so reported the matter at the people working inside where 3 days later had to go back to them and they were telling different stories about my bag being found and they are waiting for it to be returned whereby the other said the person who took my bags hasnt been found yet and that the process may take about 2months to a year... and funny enough they told me the guy who took my luggage was a Greyhound passenger... like how is that possible... and also been trying to contact the ***/*** numbers which i got from the call centre and been calling since 7a.m today and still no response what so ever. Please help me out because theres important things in my luggage as well as items for me to study plus clothing. I'm stuck with the same clothes I have to wash them before I sleep or borrow some on my friend. And it is very hard for me to replace my luggage.
