Denying me a courtesy car that I am paying for

My car broke down and had to be towed to the nearest car dealer for repairs. I then contacted discovery insure since I am currently insured with them requesting a courtesy car. I was then denied the right to have the courtesy car because the car broke down less than 100km from my home. I disputed this because this is not stipulated anywhere on my contract. I was then given the run-around from one consultant to the other (was redirected to more than 6 people who I had to explain to from the begging what had happened) and no one could assist me. The repairs on the car took 3 weeks which meant I had to use public transport until my car was fixed. <br> <br> The service I got was so disappointing and dishonest because nowhere in the contract that I signed does this clause appear. I paid a lot of money for this services and when I needed to use it, I was denied wrongfully so.
