Cell C Harassment

I have been with Cell C for many years. But in March the 3 small contracts for my kids expired and we have been running them month to month (at increased tariffs) until they decide which contracts they want to upgrade themselves to now that they are grown up. But Cell C have been spamming myself and the boys with up to 5 calls PER DAY since then. I have blocked so many numbers but they keep calling... trying to convince me to sign contracts. We all know you are desperate Cell C.. but all you have achieved is convincing us to leave your network. And when my contract expires in Feb 25, I am also gone. This complete lack of respect for your clients and harrassment is insane!!! I have explained and fought and begged them to stop. And tomorrow they just call again. You are chasing your own customers away.
