I have completed my tax return on efiling and SARS owes me money, with no (N) Audit. I changed my banking details at SARS office directly two weeks ago successfully, but when I was busy doing my return online, I noticed my old banking details where still there. I then proceeded to change them to the new ones manually on efiling. Why were my old banking details still visible there? and will they ask me to verify this again, even after I did that at the SARS office?
