Customer service

I called customer care in July 2019 to change my payment date from the 1st to the 7th of each month. Today is the 6th of February 2020 and my dstv has been suspended. I then called customer care again and was told I have to pay to reconnect. I then asked what the payment date is, only to be told that it's the 1st of every month. So they then never changed the payment date like I asked them to do. So now I must pay a months subscription plus the 6 days unpaid viewing and a reconnection fee before they will activate my viewing again. I cant believe that they do as like, after all they did not do what I asked.
