Billing and no care for customers

Please can you assist urgently. My account was not debited (debit order as I'm on price lock) for the months of September and October. I made several follow ups telephonically through the contact centre but none of the consultants could assist me. The self service option kept saying I owe R0.00. Then recently I went to their offices and I was informed that I can pay cash for the 2 months that DSTV didn't debit. I was told allxwas fine now and my usual R583 would be debited month of Nov. The self service option keeps showing an amount of R2600 which I don't understand. I called yesterday 19 Nov and was informed their system is down AGAIN! The lady Asha promised to call me today at 9am but NOTHING. She gave me this reference: *** Please can we fix this ASAP as I don't understand why I should be billed for an amount I don't understand and why I constantly have to call and go to your offices but the issues don't get resolved!!!
