debit order date

I am very disappointed that my debit order date for November was on the 23rd. I usually get debited on the 25th but November it went off extra early and was unpaid as I don't get paid this early. I get a sms that I am R300 overdrawn but my debit order went off the 1st of December 2015 but after that I still get sms that my credit card has been overdrawn. I think this is acceptable that you just change my debit order date as you please, you don't update your systems and then I get sms about being over drawn. I also app**** for a increase in credit limit and it was obviously declined because of your mistake.
