Im getting private calls randomly in the middle of the night somtimes every 2 mins everyday..how can i get them to stop?

There's no way to stop the calls form being initiated.   You can invest in a call blocker and NOT pick up on call numbers you do not recognize.

This number is calling 5x in the morning starting at 5am!!!!! How do I get them to stop?

Depending on what phone you have and whether you can completely miss all calls. On a landline, you can either disconnect the line or turn off the ringer, but you don't want the caller getting any kind of answer. A call blocker may be of some use as many have offered praise for. Search for blocking apps for a cell and see what you can do to kill the calls. As long as there's an answer of some kind, your number may be a favorite to continue hitting. They're really easy to beat if you can do it.
