Discovery Insure worst service ever!

I have been in discussions and various correspondence with the handling of my current claim. My car stood for almost 3 weeks with no one taking any action. My car hire ends now and my car is obviously not repaired. I have called, emailed etc to ask Discovery Insure to please extend my car hire since the fault lay with them and the assessor. At this moment I need SOMEONE from Discovery Insure to actually take accountability and assist me today. I never ever had this problem with Outsurance!
