Damaged Luggage and no response.

I recieved my hard shell Celini luggage bag with a huge crack after my flight to Durban. I reported the damage at Airlink's baggage claim desk and i was informed that i will need to take in for repair or replacement when i return to Joburg. I took it and I was told that I need to give them 14 days to assess the bag and they will let me know if it can be fixed or will need to be replaced. It has now been a month and two weeks and I received no feedback from them, they did not even acknowledge receipt of my damaged bag. Every time I call I am told that the person who is fixing the back is busy and they will call me back and to date no information has been given to me. I am greatly disappointed that I am the one that needs to constantly follow up for an issue that was not even created by me.
