Late debit orders,wanna cancel a debit order option as they always debit late and not on the date i gave them.

I had a bad experience with vodacom several times ,especially when there is public holiday ,they debit on the 27th when they supposed to debit on the 25th,I would normally pay them via eft on the 25th to avoid penalty fees and it still does not work .I pay them always as they cant debit on time ,send proof of payments to customer service and when I call customer care they cant find the proof of payment and i have to resend it several times .I am tired of paying for a service that i dont get.The customer service does not care and they dont even sound like they are willing to help .The service is ridiculous and i will pay them via eft from now one ,I need a confirmation that my debit order is cancelled as I wont pay the extra R100 everytime they debit late .You can see when your sales department calls us for contract sales ,they can call u too many times ,and once you subscribe you dont get that same good service ,you get a pathetic service .When you have a problem it cannot be resolved .Its high time customers are respected for what they are paying for..Fix this issue now and send me a confirmation that the debit order option is deactivated.
