Poor service at at Standard bank

My SARS refund was paid into my account on the 5th of September 2020. Standard bank is refusing to pay out until SARS validate the funds. SARS is denying such agreement. I have tried communicating with Standard bank but to date my issue has not been resolved. No one is even giving me estimated time to resolve this. Last I received my refund on the same account but this process was not followed. I feel so traumatized by this horrible experience from Standard bank. Please help.
