NON-PERFORMANCE AND UNHELPFUL TO TAXPAYERS - VAT - SARS

My company has a VAT refund due for February 2022 and SARS is not paying it, saying the reason is that the banking details are invalid. The banking details on record are those used for previous refunds hence they are incorrect. I have been unable to access their system to enter these details (they have been removed by SARS - I believe they changed their system and did not migrate taxpayer details and it is now up to the taxpayer to rectify!) Further our auditors have been trying for months to sort this out and are getting nowhere.
