Changing debit order dates with Telkom is just a nightmare!

I have been trying to change my debit order date from the 25th of each month to the last day of each month for the past 7 months - what a disappointment - if you go to any Telkom store they immediately tell you that they will not be able to assist and you need to call the Telkom accounts department - when you phone, you don't get transferred to the correct department! I even went as far as sending an email to the Telkom Consultant who assisted me when signing the contract with Telkom begging him to assist me in getting the debit order date changed from the 25th to the last day of the month - and still success! Can't wait for December to cancel my contract with Telkom, they are simply just useless! Elizabeth
