Disgusting service

I paid my mothers on the 04/02/20 unfortunately I used an incorrect ref number. I realized my mistake the same day and called to alert DSTV. In the call I was asked to send proof of payment and I did as requested. Since this DSTV has disconnected more than 5 times and the amount owed keeps escalating. My last conversation with your call centre was on 16/02/20 where the consultant couldn't explain why they keep disconnecting. She assured me that it would've been the last time. This morning the have disconnected yet again. I am tired of calling your useless call centre.

Why do you guys give us such a terrible service.
