Private Number Finder

Private Number Finder is a great service that unblocks blocked calls and restricted calls, you can even stop bill collectors and harassing callers, and you can even record the calls if you want. There is no complicated software and it works on all cell phones and smartphones.

I have used Private Number Finder to block bill collectors, and other annoying girlfriends. Even if you only use the service for a little bit, there is no contract.
