They call 7 days a weeks at least once a day but sometimes more. I've called them back and got voicemail that where I requested to be place on do not call list but of course they still call. They only identify themselves as "charity" because if you identify yourself as charity you can avoid National do not call list. Caller ID only show I.
I have had this number call my land line daily for months, I tried answering a few times and got "Is So and SO there?" that being me I said no and would get please tell them its a reminder that it was a courtesy call and they would call again. Today I got tired of all these sunday calls and late night call so I answered ......"Hello you have reached the Sex Help Hotline" and beeepppp no more caller.
So next time you ge them on the line try this and see if they will go away, "Hello you have reached the Sex Help Hotline" good luck.
