NO SERVICE DELIVERY

I settled a personal loan account with ABSA, it first took forever for me to get my paid up letter. I had to complain before I got it. Seems I have to complain for the next step to be done too. As per the paid up letter, instruction HAS NOT yet been sent to the credit bereau to update my record. It clearly states in my letter that the instruction was sent. However when i called the credit bereau myself they have NOT RECEIVED ANY INSTRUCTIONS FOR MY ACCOUNT. ABSA is the worst bank ever!!!
