PATHETIC SERVICE FROM ABSA

What I though will save me time and my credit turned out to be my worst nightmare, I have arranged a debit order 4 Months back with ABSA. Since from day 1 they mess it up . They did not debit then it was not activated then I was in arrears then they will take the money on the incorrect date. They suppose to be professional but all I hear its excuses and again now I m in arrears and their reason is the person who did it 1st time did it wrong. So basically I m being penalized for ABSAs mistake ? This is a horrible service
