Delayed baggage, delayed delivery and no contact

On the 26.10 I took a flight from Warsaw to Johannesburg, via Paris and Addis Ababa. I realized in Johannesburg that my luggage did not arrive to the destination and that it stayed in Paris. I spoke to an officer at the Ethiopian Airlines counter and filled in the form (reference number: JMBET 29742). I was told my bag will arrive to Grahamstown (which was my final destination) next day (28.10). On Saturday, the 28.10 I received a call saying that my suitcase will arrive only next day (29.10), with the South African Airways, flight number SA405 at 10:45. I was supposed to receive a confirmation phone call today and the bag was supposed to arrive to Grahamstown straight from the flight, which would be at 2 PM. Nobody called me and I also cannot reach any out of four phone numbers I was given with my form. I do not know, when my bag will arrive and I was not offered any kind of reimbur*****t for the delay. I cannot start working as my working materials are all in the luggage. I also do not have my personal belongings such as clothes and toiletries, which made me spend money on them.

I do not know, how to reach the offices in Johannesburg and I do not know, when I will receive my delayed luggage.

It is first and last time I flew with Ethiopian Airlines!
