Frustrated by Discovery Insure

After receiving several notifications from Discovery to change my DQ trackers for my cars (which were both working fine by the way, for the past 2 years) I heeded the call and went to Tyger Wheel and Tyre, Willow bridge, Cape Town. After an hour of attempts and phone calls to Discovery, we could not link the new tracker to my car. The next day I continued with the attempts but to no avail. I then called Discovery again and spoke to Samuel last week. He asked me to leave the office and go to the car to try one more time because it was now sorted. Unfortunately, it was to no avail. I was then assured it would work after 5 hours but again it did not. The next day I called again (for almost 20 minutes again) and spoke to Lebo, a team leader. She again sent me outside to the car to try and connect again because "it was now sorted." I tried again but to no avail. She promised Discovery would call me back. Days went by, and in all this, I was losing the Vitality drive points, the reason I joined the insurance. After waiting and waiting I decided to call them again today. Just spoke to Bongani and again he sang the same chorus, "go outside to your car and try one more time because we have updated on our system." This was just another goose chase. I have lost a lot of time sitting with them on the phone, at my cost, lost a lot of mileage on my profile because I have no working tracker, and I am totally frustrated by the way Discovery has treated me, especially having been loyal to them for nearly 2 years. Reference number for the case is QC201109
