Second Post, Two Weeks, Still no service.

This is the second time I am posting a complaint on Discovery Insure in two weeks. Discovery has failed to attend my booking on Saturday the 12th of March 2016 for my DQ device. They arranged to come and install it on the Thursday that followed and still no one pitched or informed me anything. I have emailed them and explained several times to them that I am going on holiday and that needs to be installed before I am going. Ref ***. They actually tried to contact me ONCE while I was on holiday and thats it. If this isn't enough they have promised me that I will at least get R100 back every month and because I have no device installed guess what, I am not getting anything back. This is insane. One last change and I am going to cancel my policy with them. Never trust any promise. If there is this lack of service with only the initiation of the policy what will happen when I need to claim with them? <br> My new car was vulnerable because of them while I was away on vacation.
