Bad service

I have comprehensive vehicle Insurance with integrisure. Was involved in an accident on Friday 14 June 2019. As Part of my comprehensive Insurance i Pay for the use of a courtesy vehicle When my vehicle is not able to be made use of after an accident. I tried calling on Saturday morning 15 June 2019 to arrange for à courtesy vehicle as my vehicle was not able to drive. I got told that i would have to wait until Tuesday 18 June 2019 for the brokers to arrange a courtesy vehicle for me as it is a long weekend and the offices are closed. As this is my only vehicle it is imperitive that i need a courtesy vehicle immediately,which i pay for ever month on time and without fail.How is it possible that the broker accepts that vehicle accidents only happen on normal working days and not on weekends. This is what it seems like as there is No option to make use of after hours for emergency situations like mine.
