Very bad experience especially with stretch and Dant insurance

Very bad experience especially with stretch and Dant insurance. I asked for my car to go for repairs and I was charged approximately R6000 which was more than the cover of which I was expected to top up. On the day of repairs I was told the they will only repair a very tiny stretch for that amount which was very ridiculous. I asked them not to proceed with the car and cancelled the insurance. It was a waste of my hard earn money and this stretch and Dant insurance is useless and a reap off.
