Bill - Part of our mission is to help people who are in trouble with their mortgages. When we were looking for an easily recognizable number for our non-profit mortgage assistance activities, we came straight to you and got the number we wanted. Thanks again.

I cant thank you enough for helping make this such a smooth transition. I had another toll free vanity number that was lost in the shuffle! After lots of aggravation of not being able to get the number back I decided to contact TollFreeNumbers.com. Everyone was helpful and followed through with every promise. My new toll free vanity number is up and running and I have all documentation to prove that Im the rightful owner! Thanks for all your help! Mike Feazel
