Unsatisfactory Service

In 2024 when I conducting my Tax Returns, SARS Advised that I received interest/ Earnings from Capitec Bank.I had to send a dispute to SARS and uploaded a closed account letter ,SARS declined the letter.SARS wants a letter that stipulated that I didn't receive any Interests from Capitec and they need to remove the third party information.When I visited the branch they could get any information from acc *** and when I contacted Capitec Head office they wanted me to open the account to be able to be able to assist me.The consultant at the Brits Mall confirmed that the accounts that start with 21 are recent accounts,but still they cannot assisted me for 2nd time as again the Head Office was contacted.I am really upset as SARS referred me to them as the banks are they one conducting returns from their side.I paid 105 000 to SARS including the R6085 that SARS said I earned the interest from Capitec. I need this to be sorted out as soon as possible as SARS need that letter
