No wonder SARS is also the name of a disease

Apart from the opportunity to vent some frustration, there's not much point in writing this about an organisation that I have no alternative to being a "client" of, but I'm going to do it anyway. After five months of battling the call centre, and two months after filing a complaint with SARS's own complaints department, I have today yet again received a new date by which my simple tax return as an individual will be finalised. When that date arrives at the end of the month, I will no doubt again receive some vague promise of yet another date, yet another twenty-one working days in the future, yet another complete absence of any feedback apart from yet another call centre agent "escalating" the matter to some manager or department or process, never to be heard of again. I have now been advised to lodge a complaint with the Tax Ombud. If doing so will make SARS even just half as vindictive and spiteful as they became after complaining to their own complaints department, I doubt if this will get me anywhere, but what other choice do I have?
