DSTV DEBITS ACCOUNNT WITHOUT INSTALLATION

I am a very dissatisfied customer. We have app**** for the DSTV Xplora for about R 595.00 per month on the 20 December 2018. I have made numerous calls, visited the Umhlanga Rocks branch and to date we have not received any feedback. DSTV even started debiting my account without installation or delivery of the new decoder. But if our account is not paid our services are disconnected but now without the services our account is be debiting. When I called the call centre yesterday (17/01/2019) I was informed that since they have the banking details they can debit our account. I then informed the agent that if the Xplora is not installed how can they debit my account? She could not answer. Very unprofessional services.
