SARS failing to act on their staff

This Standard Bank *** was used for SARS ********** refund activities concerning my refund. A month later SARS is still investigating and no feedback. SARS confirmed my banking details were changed on e-filing after my submission was concluded. And then changed back after the refund was paid elsewhere. A month later they cannot recall my refund or provide progressive feedback. Maybe because their staff is involved and this is and internal problem??***
