Useless travel logs

Part of my Netstar package that I signed up for, is receiving a monthly travel log to see where you traveled during the month. I live and work in the Western Cape, so its should be quite easy to track my movement. This is quite a good idea, but very inaccurate! Once they had me in Mangwato, Galeshewe Ext 7 which is Kimberly, and another time in Lucas Mangope Drive, Mabopane U (this is in Tshane!) both places that I've never been in my life. What use is the travel log if it is not accurate?
