Lack of communication and service

I completed my filing as soon as the tax season started. I was asked by SARS to upload supporting documents, which I did. I understand the audit process takes 21 working days to complete. I called the SARS Customer service number 3 days after uploading the docs to find out if everything was OK. I was told there were further documents required. This notification was never sent to me. We are now sitting more than a month later and still no progress has been made on my tax return. Had I owed money to SARS, I have no doubt they would've been hounding me for it, but now that it's the other way around, they seemed to have let "sleeping dogs lie". I really require assistance with this. SARS Please get your act together and sort this out.
