Disgusted!!!

I have a personal loan with the above bank. I had signed a debit order for the monthly amount to be deducted from my cheque account directly. This debit had not been taken from my cheque account, which I was not aware of as I was not monitoring for this, as I had signed and organised a monthly debit order with them, when the loan was taken out. Now over the past 6 months or so, I have been contacted by ABSA to EFT my repayments on a monthly basis, as well as the arrears amount. I have been in contact with the Call Centre whom are totally unable to assist in any way shape or form, and have directed me to go to the branch! I have been to two different branches to have this debit order sorted out, but they are also unable to assist me! I have been listed at the Credit Bureau for having bad debt due to ABSA's error! Where is your service ABSA!!! I have been a client for over 20 years, I am disgusted at your inefficiency and total lack of care! I INSIST I get contacted by someone in a senior position, this debit order sorted out and my name cleared at the Credit Bureau, and the interest you charged me for late payment!!!
