There is no list of numbers not to call.being with the dozens of calls they make each day.The manager needs to give a list of the names of people that dont want to be called.Cause companies just recycle the same numbers & pass them out again in 6 months,because they think just because one person said no,they think they will say yes to the next person that calls  a few months later.I know for a fact that isnt true.I did this crappy work,when someone tells me I'm not interested  I dont push it & do cross the number off, but others may have a copy of that same number which sucks.I called businesses not homes,so I dont know how that works,but find out the company name.then call them back & tell them not to be called & they should tell the room dont call this person any more.I hope this helps out.
