Harassment -AND I do not even insure with them

This is by far the worst insurance experience i have ever had, and i don't even insure with them! i had a car accident with someone who was insured with telesure. (It was not my fault). I have claimed with my insurance and they payed out in no time and was amazing(Nedbank insurance) No long and tiring phone calls and no problems at all :) TELESURE on the other hand who i have no dealings with keeps calling me and harassing me for information, i have given them all the details of what happened during the accident but still calls me to ask me the same questions over and over as if they are deaf! This is the worst insurance company i have come across and i would rather not be insured than deal with them as i can see how poorly they respond to their claims. I am at the point where i had to download an app to block their number because they keep calling me to ask me the same things over and over; "What happened that night of the accident?" how many times must i tell you???!! and why cant you call my insurance and liaise with them. Leave me the hell alone man!
