I recently started receiving calls from this "anonymous" and googled it to find it was The International Fellowship of Christians and Jews, which is a valid cause & have given to in the past, but did not give them my number & don't appreciate the harassment of calls (probably automated)...so i researched on their website and found their contact email( @ifcj.org )to reply to them to stop calling...I will see what happens.
Thanks, l will try that web site. I also get calls from them with 866 area code. I don't answer but they continue to call . Can't think of how they have picked me?
