SARS
Never notified of an outstanding amount

Last week I received an sms from SARS saying that if I don't pay my account they will take legal action.
What outstanding amount?
Apparently, from my 2011 tax submission.
This is the first time I hear about it. I submitted my 2012 submission with no problem. Nowhere did they say I owed anything.
Now they have heaped on interest and want to take legal action.
Very poor show SARS. Get your admin in order.
I am very disappointed since I always do my returns on time.
