Continues disconnection of dstv in month

Good day<br> If I can count, I think my dstv has been disconnected at least twice a week for a day or two this month. Multichoice claimed that I did not pay my July account and after sending the proof of payment to them more than 10 times to different email addresses and making endless calls, they connected it just to disconnect it a few days later. I think I paid more for emails and calls than my monthly subscription! This morning when I turned my dish on if was disconnected again. I am not sure what proof to send them anymore. I am now not sure if I should pay my subscription tomorrow for August.
