I have an unlisted number and still manage to get one now and again. I don't ever give out my number stating it is unlisted instead. They don't ask further. For e-mail I give an address I keep for just such a purpose and surreptitiously delete all those. It is nearly impossible to avoid those calls altogether, but it does help in that respect to be unlisted.
