Incorrect Information Loaded by Capitec Bank

In 2018 i called Capitec Bank requesting information as the bank has listed me as a default payer , they could find no information and i was advised that they will remove the incorrect information. Called again 29.05.2019 as my credit report still shows i owe Capitec money only to find out again that they cannot find any records, ref no: ********** 1 was given to me as i need to send a request to state that i do not owe Capitec Bank any money . I cannot wait 5 working days to get this letter . Please help
