I never get them on my mobile (touch wood), but we keep getting them from time to time on our home phone, which is a VOIP number we've had for about 5 years. When we first joined up to our ISP and got the number, i'd asked for it to be unlisted, which was a free option with them. A couple of weeks later, I got a cold call from a company selling window shutters and wondered how on earth they got our number (which they wouldn't tell me, of course). Checked the online White Pages and was horrified to find our number was listed, so immediately rang our ISP who were very apologetic and had the listing removed immediately. However, 5 years on, we STILL get marketing and scam calls on that number - despite the fact that it was only listed online for a couple of weeks, was never in the printed copy of White Pages (I checked the next one that came out!), the only people who have the number are my parents and Mr Jurahn's parents and I listed it on the Do Not Call register as soon as I received that sales call. It seems once the number is harvested and "sold on", it keeps doing the rounds for all eternity.
