Discovery SPAM calls that DON'T STOP

Dear Discovery ALL DEPARTMENTS. I am happy with my discovery medical aid. But can you please remove my number from your system and stop trying to contact me a few times a week. I am not interested in anything else you are trying to spam me with. My truecaller is working over time trying to block all the different numbers you use. If I get one more phone call from you trying to sell me something that I didn't ask for, I'm reporting you to the Department of Trade Industry and Competition.
