Mango not taking customer service serious

I flew with Mango airlines from George to Johannesburg. My bag was broken into and the zippers cut so that I can not lock it anymore. Mango gave me a loan suitcase and offered to fix my bag, but unfortunately they did not offer to get the bag to me. That means that I would have to drive over 100kms to the airport and spend my money on our country's very expensive petrol to fetch my bag. Mango, I am sorry, but that is not good enough. If you cannot keep our baggage safe, you should at least have a service that deliver our bags to us when our baggage was damaged whilst flying on Mango.
