ABSA ********** or *******

In 1993 I had a student loan with ABSA/ Volkskas bank and the took a session on my life insurance policy. I have long since paid of the loan, and have been battling with ABSA to remove the session on the policy for more than 21 YEARS. I have gone to the bank numerous times and have sent numerous emails, asking them to remove the session. I filled in the same paper work over and over again but without any results. In my last email I asked them to mail the contact details of the Om budsman and to give a reason why they wont help me. You can only go to the ombuds man if ABSA's customer service cant help you. They refuse to answer my emails, and ignores my requests and in this way leave me without proof to take the matter to the ombuds. Now I ask you, is this *****, incompetency, ignorance or just plain thievery. Why are all the banks in South Africa above the law? Maybe they are part of the government and do anything they like without any consequences.
