Upset with SARS service

My tax return was done last year 11 November 2015 on efiling, which I found I did something wrong and had to go into the branch to submit all my documentation. I waited over a month for my return to be audited, only to find out without an phone call or email from SARS that I needed to bring in an affidavit stating I was unemployed for 8months as an estimated amount for those months was just established without my knowledge and I now owe SARS, I called almost every week to find out the status of my return for 2015 and all they ever trained to tell you is you are still in the estimated turn around time, you complain and it's the same thing. Their service is pathetic because the customer care line SARS workers can't even inform you on the status either. I waited over a month and now due to their error and wrong judgement I must now wait another 60 days for my objection to be sorted out what ********!!! why wasn't I called or emailed before they found it upon themselves to estimate and not forgetting that they can see the months I worked on the company forms. I refuse to pay them the estimated amount by the date given as my query is not resolved and clearly no one can help you.
