No Help with debit order reversal

On Sunday the 1St of February DSTV debited my account without my authorisation. I have given them permission to debit my account for R100 each month for my subscription with them. They debited my account three times with the amounts of R673 , R673 and then R1413.81. I was on the phone for a hour on Sunday and was transferred to so many different departments who couldn't help me. Finally I spoke to someone from the authorisation department who said they would reverse the amounts within 24 hours and gave me the reference number of ***. The transactions have still not been reversed so I called today. I very nice lady tried to help me but said she couldn't and gave me another number to call. I tried calling that number the voice prompts don't relate to my problem and I am tired of wasting my airtime now when this should of been sorted out on Monday already. Please assist me with this matter.
