Terrible service and empty promises

I have been battling with dstv since 23rd September. At first it daily, last week it was twice and yet today again. They didn't allocate my payment for days then switched me off for non payment. Today they switched me off again. Every time I call in I have spoken to supervisors, managers and agents. They switch me on promise to reverse the reconnection fee and it won't happen again and yet today I was switched off again for there error. I called in over 16 times since 23rd September 2019 for the same problem. Why am I being inconvenience because they can't do there work and how do I even get to the bottom of this.
