Which brings me to the "SARS" letter I received last week. The letter itself was quite interesting stylistically, being a "Your deductions from 2006 are being re-examined, please send supporting documentation or call
I assume (based on very little evidence, but inferring from the tone of the letter and the emphasis on phoning them) that this is a "pay us to make this all go away" scam. If that is true, the people running reckon that there are enough people who are somewhat guilty about the deductions they've claimed and/or sufficiently convinced about the corruption in the system that this strikes them as an acceptable approach to getting rid of the problem for the scam to be profitable, which is an unflattering assessment of modern South African society.
Also, given the times-scales involved - probably a week to allow for letters to arrive, a few days for the people who are going to call to call, and them some time to talk them into something that will pay money, it look likely to tie them to an potentially identifiable number for at least a few weeks. Since they cannot be assuming that no-one will realise this is fake and report it, either this needs to move to the paying money part quickly (and I'm not seeing how they'd do that) or there's something in the risk mitigation part I'm not seeing.
