CAPITEC Unable to Change Debit Order Date

I am having an issue updating my debit order date for my credit card. I have contacted the Call Centre which advised me to go into a branch. I went into the branch at The Grove Mall in Pretoria and the consultant could not or did not know how to change the date and advised i need to come back with all my documents to "Restart" the credit application again in order for the date to change.

I really do not understand this logic! How can your consultants not know how to change a date?

They have inserted the incorrect date since i got the credit card and this has affected my credit rating as they are trying to debit the account 2 days before the actual date and keep receiving threatening SMSs stating "Failure to settle your arrears NOW will affect your chance of getting credit"

I need to get this date updated URGENTLY!!!!
