No service from SARS

I submitted my returns on the 01/07/2018 for 2016, 2017 and 2018. 2016 and 2017 was selected for audit. 2018 will be manually processed by sars within 90 days because of an outstanding tax directive. Nothing to be done on my side just to wait the 90days. 2016 docs requested was submitted on 17/07/2 ********** docs requested was submitted on 10/07/2018 They explained turnaround time for an audit case to be completed is within 21 business days. for the 2017 audit 21 business days was already on 09/08/2018. we are on 16/08/2018, still not finalized, still showing busy for more than 2 weeks. escalated still nothing is done 2016 audit case that 21 business days would be by today 16/08/2018, still showing busy Why is this taking so long? Sars takes your money that you work for the whole month before you even get to touch a cent of it. But when it comes to them playing their part nothing happens. It's like most government places they do not know the meaning of turnaround times or escalations. They are forever on holiday. I feel for the call centre because they have to give answers when they do not have any because their colleagues in the background are just chilled
