I was just wondering, why do service providers,banks and some other agencies always ask for Mother's maiden name during registration. MTN is currently asking customers to update their mum's maiden names and they get #400 in return. Now, who wouldn't. What baffles me is that of all the information they have from registered sims, why does it have to be maiden name that needs updating. Probably,it's the most important. Anybody with answers? Thanks.
