Hyundai South Africa - no sense of importance when to comes to customers

My mother's car was towed this morning to a different dealer than the one we requested. The dealer then called and told me that they are closing tomorrow at 12/1pm and will probably look at the vehicle on 6th January 2020. When requesting that they provide my mother with a loan vehicle for the duration because apparently Hyundai doesn't hire cars for their drivers like other brands. The dealer told me that they don't have vehicles to provide. I then proceeded to call the head office to tell my main worry is that mother has a heart condition and needs a vehicle at all times as she has frequent attacks, the lady I spoke to just told me that there's nothing they can as the head office. My mom's health and safety is of no importance to the company as their customer relations is at the pits. I further asked if the head office can't instruct for the vehicle to be towed to a dealer that's not closing over the holidays and I'm told that will be for my cost despite my dilemma I explained earlier. I'm disappointed and disheartened by lack of empathy for an elderly woman from the dealers and the head office,to them it seems like my mother should rather die than them assisting in way.
