bad bad service from multichoice

Good day

Multichoice debited my mother's account on the 29-September 2018 her CARD NUMBER IS ********** 1850 but they have now closed her DSTV we called several times. there was a consultant that called her asking to load a debit order on her account she refused because DSTV has been debiting her bank account for the wrong decoder without her consent the consultant loaded the debit order we then called on the 30 and told them the debit order was not supposed to go throught the consultant that assisted said we should not worry cause the debit order is loaded on the right profile i told the consultant that after the debit order has gone through we are receiving a message on the Tv screen and sms's that we should pay and she said it's just an error now we don't have access to DSTV yet the mney was debited we've been calling the call centre we are not getting any help.
