They're using a bunch of 480 numbers. Thank goodness you can block them for free with an inexpensive VOIP service. It's cheaper and better than the phone company's charges. You can get it now for less than $10 per month. Go here to learn more: http://www.tandemmarketing.net/phonepower/
i had been signing up to job sites and it was the scam that some place they wanted you to get further education - i never checked the box for further education ... but they kept calling me lots - so i called them back and told them i did not need the education and told them to stop calling ... so fat i have not had any calls from them - they also wanted me to or thought i had signed up with jobs.com and during the phone conversation i had with the guy on the phone ... i went to the web site and realized i had never signed up to that web site for jobs ... and will stay away from it
