Disgusted

So once again my debit order returned on my account. My home loan repayment is on the 25th of each month. It was changed by someone at Standard Bank to the 20th of each month. Logically if I get paid on the 25th of each month I would want my debit order to run on the 25th. I called Standard Bank call centre to rectify this matter and the advised it has been changed. To my supprise the debit order went through on the 20th again and no one has given permission to debit this account on the 20th. Standard Bank just does as they please and who has to carry the cost? The customer, I asked them to reverse the DOR fee which they did not do and they simply just ignore your requests. So I guess im now R230 poorer and again I have to call Standard Bank call centre at my own cost.
