Prescribed account not removed

I have been in contact with African bank since March explaining to them that an account has prescribed and need to be removed from my credit report. African bank came back via Basani Mathebula who is a supervisor for legal collection to tell me that the account has not prescribed and i then asked for proof to ascertain what they are saying. A month later I recieved recordings from Basani. On the recordings...there are two women communicating. The caller was looking for me and called a certain woman who confirmed that she does not know me. I have since reported the matter to the credit bureau cause this is disadvantaging me. I want to urge african bank to remove the accounts and provide me with proper evidence against my claim of prescription, failure to do that within 5 days will cause me to contact my attorneys
