Sars is the worst

I am really sick of Sars and don't understand them. They a u to assess me every year but revert my bank details to a dormant account I have not had in years even after they receive ur bank tax form, irp5 from ur company, medical details all info which reflects your bank details. I had to update it last year to my active Fnb account I had for years as shown on all my docs submitted to them (Sars). I was asked to send a million supporting docs to prove myself last year I order to get the balance of my refund after they took a chunk of money which we dnt need to prove ourselves for. This year again they auto assesses me and again reverted my bank details to the old dormant closed standard bank details I have closed that account many years ago. Now again I had to update my bank account details which they have coz they receive info from ur bank and again asking me for a millions docs to pay me out when this is not my mistake they auto assess u with wrong info when they receive all the info coz ur bank, medical aid all those ppl submit docs to them. Why must I update my bank details to my 1 and inly bank account in record every year? I hate this system it's daylight *******. I would rather not be auto assessed coz every year I must suffer like this. If this happens again next year I know it's a trick to delay an possible payout as this is jst so strange that every year I must do the same old **** and my bank details have been the same for years, where do they even get this info, I called standard bank and they said my account is closed years ag so they wouldn't send any info to Sars eish. Now I must wait until Jesus returns for a refund, but I dnt need tj prove myself every month wen use want tax. I hate this company *****s
