Frustrated customer getting no assistance

Getting frustrated with Standard Bank and the run arounds that are not yielding results; I realised in 2016 that my account has been handed over (of which i thought was fully paid). After inquiries with Standard Bank i got the contacts of the attorneys it was handed over to and made arrangements for payments.

Problem now is I made a credit check report and still find that this amount is still reflecting on my ITC report. I am now being given a run around by Standard Bank on who to liaise the account with: >I was first told the account is with NBA. They told me the matter was closed in August 2016 and should liaise with Standard Bank. >Then I was told that the account is with Real People. They tel me they don't have such an account. >Then I was told I should contact the attorneys(Norton) whom I was making the payments with and inquire about the payment because Standard Bank cant see details/ history of the payments. They tel me that the last payment that was made to them in July 2016 was never updated on their side because the account was sent back to standard bank in June 2016. >Then I was given the legal departments email to liaise with, and I now get an automatic response saying that the email is no longer available to customers.

I have now reached a dead end and don't know where to get the help from. This is frustrating since it is affecting my credit record and should have been clear long in 2016.
