I do my utmost to keep my personal details personal. However, if the DA managed to get hold of my new cellphone number, less than amonth after I changed it, what chance do I have? The *person* that caled me said the number was obtained from the 'national consumer database', which means that somebody, somewhere, in their official capacity, is making money from onselling MY PERSONAL information. The only people that had this number on record at that time, was VOdacom, and ABSA bank. I know for a fact that banks used to sell contact info to marketing companies - don't know if it still is the case.
So in summary, to those that make all these kuk rules to keep us consumers in check, start where it matters: regulate and penalise financial institutions (not just banks, I include retail stores, financiers of every description, municipalities, credit regulators, the lot) for failure to protect their customers' information.
And to all those morons that fall for phising scams, well, good luck.
