You can forward email and phone calls from services that provide a bit more privacy. For example, such services should allow to block the address/number from which the forwarded email/call come from; such services should be either free or collect payments via Bitcoin, and in general collect the minimum data required in order to provide such a service.

(I am new here and am not sure whether I can refer you to a service that we have built. When I tried to submit "Show HN" I was not permitted to post.)

Not having a cell phone would probably be your best bet if your looking to hide something. If not, campaigning for a senator/congressman who will work on changing the current flawed NSA.
