Negligent, Damaged luggage & not will to assist with interim solution

I received my brand new hard shell luggage bag with a huge crack & 1 of the wheels broken after my flight to Cape Town. We paid for travel insurance & seemingly no one knew how their insurance work.

I reported the damage at Airlink's baggage claim desk. I later received an email stating "You may drop the damaged bag at your convenience at the Airlink office or at the Airlink counters at Domestic Departures (counters 40-46) at Cape Town International Airport."

I asked them if I will have a temporary bag as I am traveling to Springbok and i do not have another luggage to put my clothes. I received the following response form the airline through Alexi stating "I am sadly informing you that we do not keep replacement bags here in CPT."

I feel that since the negligence came from the airline, then they should help & come up with a solution on how as a paying customer i will be assisted in the interim.

Basically what they are saying to me is that I should figure out the inconvenience they caused me & that THEY DON'T CARE HOW I CONTAIN MY BELONGINGS whereas I was grieved by their services.
