Went to a Edenvale SARS branch on the 30 Sept 2016 to do my tax return and I had all papers except the bank statement and I went to submit it on the 3rd of October 2016 and I was told to wait in less than a month then my returns will be in my account but until today I haven't seen anything, I called them on the 11 November 2016 to ask if there's a progress or what. They told me I was under investigation and the guy told me to submit the bank statement, certified copies of ID and proof of adress again to the branch and they will start the process cos those I submitted before was for investigation not really for my return. The thing is why wasn't I told about this then only to find out a month later yet I received an email from SARS that this is how much they owe me and it will be in my account. But now it's a different story altogether. I'm not happy someone isn't doing their job and should be send back for training
