Harassment by MiWay

I honestly don’t understand this company and the way they do business. I was called by an agent, unbelievably unprofessional just by the way. I asked her to please stop calling me(I’m assuming that would automatically put me on DNC) but she asks me why do I want her to stop calling? I instantly hung up! On the call you can hear me clearly state I don’t want to be contacted, I said it TWICE! Guess what? 30 minutes later I get another call from MiWay! You guys call me every 30 minutes of everyday and I don’t even know where you get my number from because I have never shown interest on any platform regarding MiWay. Whatever you guys are doing is boarderline harassment and breach of POPIA. Stop calling me!!!
