Failure to close loan account

I am extremely unhappy about the service I have received to date in an effort to have a loan account I had with Absa closed to date. The loan account was linked to a debit order and end of May 2015 was the last debit order. Unfortunately, there was an outstanding amount as I was receiving text messages from Absa. I then called the 086 number as per the sms to enquire and I was informed that I owed 1c. I was advised to go into the bank and settle it. I went to Absa Rivonia and spent over an hour and finally settled with 10c. The branch indicated that they would call the loan department to close the account as they could not close it from the branch. Ingrid informed me that she would call me once done but she never did so and the number to the branch is always engaged or no one picks up. I continued to receive text messages from Absa loans and in July I called again and I was informed that the outstanding amount was settled but the account never closed. I was promised that it would be closed. August 06 2015 I received another sms and the account is still not closed. ABSA, I am a customer for many years and I DEMAND that this be resolved asap it is not my fault and this is INSULTING!
