Car Insurance claim

I am so fed up with Iemas. My claim was first not registered in full therefore I have been driving around with a chipped windscreen. A week after reporting my claim only then do they send my policy schedule to my insurer, the information that was sent to my insurer was incorrect. My car is a 2017 Model not 2016 furthermore the claim details are incorrect. I received such bad service from Iemas as a number of times did they hang up on me. My screen is still chipped and to date has not been fixed. I am paying over R2500.00 to Iemas monthly for the worst service ever
