Very Bad Service received without any assistants at SARS

We have been trying to get hold of someone at SARS to contact us back over the pasts few months, leaving messages and sending call back requests, in regards to the release of my husbands SARS refund as they requested documentation to be submitted about 5 months ago or last year. I submitted all and since December 2020 they all of a sudden stated that his 2019 SARS year has been placed under audit, which in the same breath was already paid out and settled. I want to know why and and when the rest will be released. I need someone to call us back in this regards as I feel that they are uncapable to get back to any person who has a query regarding anything that goes on at SARS. I need an answer as soon as possible, even today will be better.
