If you receive unwanted calls all the time, consider installing a call-blocking device. They can be installed directly on a home phone and most of them use blacklist databases of known spam numbers and allow you to add additional numbers to be blocked. Also, there are blocking devices which you need to configure manually, by creating your own blacklist and updating it constantly.
Consult your operator on how to obtain, install and configure a call-blocking device.
Go to Settings (swipe to the left to access the apps list) and scroll down to and tap on Call+SMS Filter.
Move the slider under Block calls + SMS to the right.
Go to call history by tapping the phone icon on the main screen.

Every operator offers a call-divert feature, allowing you to divert phone calls from one number to another. If for some reason, usually by mistake, someone has diverted their phone calls from their phone number to your phone number, you will receive all the calls directed to their number.
