Why is my Galaxy s7 calling random phone numbers? Help fix?

[AC Question]

This has happens on and off over a few months. But my Galaxy s7 has been calling RANDOM phone numbers with the same first 3 digits as mine. I dont know why it does this or how to fix this. But there has been a lot of angry and confuse phone calls.

Please help me figure out why this happens and how to fix this.
