Try 4-5 times per day and it is a scammer.
I am on the don't call list but a few of people get around it. Adding your number to on line companies allows them to sell the number. I usually use a bogus number....

Stop these calls

This phone number calls 2 to 3 times a day. What a pain.

This number calls my house 2-6 times a day for the last two weeks, and been asking for different people who don't stay here. We asked them several times to stop calling, but they wont.
