Bad Customer Service and Stupid Billing system

I have a debit orde running with them it happened due to unforeseen circumstances the debit order reversed called in to inquire what can I do to rectify I was given bank details paid the amount reversed that was 1 November. On the 24th November they debited called to enquire why cuz our agreed date is the 1st of each month I waas told is due to the reversal therefore online collection is deals with the account going forward that won't be the case said their consultant ,again on the 15th those online collection attempted to debit again I called and enquire. On the 20th December again the online collection debited but my kine is block till today. I called I was told about 7 working days I mean which bank takes 7 working days to clear funds. Ive had enough of Telkom with their incompetence and unprofessional patterns. I can't wait for my contract ro be done. Pathetic service
