Cancelling of subscription

I have been trying for over a month to stop my subscription with Multichoice. Now that there is a lockdown, it is impossible to get through to the help lines and my account show that I am due R904. I have stopped the debit order with the bank, so hopefully the money won't be deducted automatically. Poor service even though I cancelled before the lockdown and 2 different operators assured me that there won't be any further deductions as DSTV is paid in advance.
