On some information I was reading on scams it had, while your telephone is ringing,
take the reciver off the hook, push the # button 6 or 7 times quickly, and that would
take your number out of their data base.
I would be careful about pushing a number, as there was a scam using that,
then it would transfer your telephone number and they could make calls, using your #.
Maybe that doesn't work anymore.
Would be interesting to know if it does works!
This number calls several times a week. Some I have answered, some I have not. They never leave a message and when I do answer no one is ever there. Wasting my time!
