Its been more than 21 days since I've been on audit, how long does it take?

I submitted my 2013 IRP5 this year. It was sent for audit and I was told it will take 21 days. I haven't heard from SARS again. No updates none whatsoever. How long does it take for audit and how does it work?

When did you submit, please read our blog on why you may have a delayed refund from SARS
