Poor selection of partners to share my information with

Very happy with DSTV as a product. I am a premium subscriber, love the sport and the programs on offer. Maybe a bit too many repetas etc but I can live with it I recently upgraded my decoder through OnAir. Process was smooth. However since the upgrade I cannot get rid of people calling me trying to sell me insurance. I did not opt in for this. The worst thing is today someone called congratulating me for being a long-term subscriber and made it sound like I was going to be rewarded for my loyalty (I am not that naive to expect something free) and proceeded to tell me I had access to a special insurance offer for funeral cover for me an my family at only R119 for R50000 rand cover. DSTV need to select who they share information with more carefully. I do not want unsolicited calls, especially sneaky underhanded calls making it sound like they are doing me a favour when all they are trying to do is sell me something. It almost makes me want to cancel my subscription and go to another platform.
