DSTV FAILS TO DEBIT BANKING ACCOUNT AND DISCONNECTS SUBSCRIPTION! ****************!!!!!!!

I have a debit order against this contract, however, on 31 August 2019 I was informed via SMS that they have stopped my DSTV subscription due to non payment. Furthermore, the debit order usually goes off on the 2nd of every month. The debit order was collected on 02 August 2019, however, it was not taken on 02 September 2019 - WHY. Trying to get hold of them is an absolute nightmare and their promises to get back within 6-8 working hours - (I lodged a query via email) on 08 September 2019 - and to date, I have received absolutely nothing via email, except another SMS informing me that they have stopped my DSTV due to non payment. Surely if a debit order is in place, I am not to blame for them not collecting the funds - and yes, there was more than sufficient funds in my banking account for this debit order. This organisation is seriously monopolising the industry and treating us all like ****. They do exactly what they want to do and they are now holding me liable for the reconnection fee. Can somebody with a bit of brains at DSTV-Multichoice, kindly respond to my email queries. I am currently abroad and only available via email. I would like my subscription switched back on without the reconnection fee debited to my account as I have for the past couple of years had a debit order against my profile.
