said by JackBauer:I think having your phone number unlisted for 26 years also helps, in addition to being on the Do Not Call list. I rarely get marketing calls.
Everything from my college annual fund solicitation, to TWC trying to sell me their phone product, to political solicitations and fundraisers... To people who ignore DNC.
Heck I probably have more than 30. Once someone calls, I screen, search google, and block if needed. They never get through again.
I've actually left the country for ten days and came back to not a single call while I was gone.
