Wrong Debit Order date

I have a credit card with standard bank, for the past 4 years my debit order date has been the same, last year 2015 October my debit order went off earlier then it should have so obviously I hadn't been paid and there was no money in my account and as a result my credit card was blocked and I had to go into the bank to sort it, we are now in January 2016 and I'm still having the same issue. I have called and always try to sort out the issue and I get told that as of next month it will go off on the right date but every month now seems to the same issue I am highly annoyed by this and now I was being handed over to McRoberts attorneys for something that is not my fault!!! As I spoke to one of the consultants who thank God was honest enough to say that there was in glitch in the system that auntomaticallg changed debit order dates. What irritates me the most is the fact that Standard Bank did not call their clients to warn and notify them that this is what happened! Messing up with our credit records we still want to apply for things where our credit records and ratings need to be checked and such a thing creates a bad reputatio. I personally would like a letter of apology from you.
