KEEPS CALLING MY CELL PHONE AND DOES NOT LEAVE A MESSAGE

This company sells trucking accessories and heavy industry supplies. They always call and say " you a tough guy to get a hold of, aren't you?" The same cheesy line every time. They almost always swear at me when I ask them to take me off of their call list. One time one of their guys called me during the day, cussed at me, hung up on me, then called back at 2 am while my wife was going into labor with our first child. When he called the only thing he said was that I had a small penis, and then hung up.

The caller hung up when my answering machine started my outgoing message.

They want to talk to hausfrau.

no one on the line, but have received threatening phone calls from an "indian"/Muslim voice. 5 calls received today!

All days and nights bother me. stop or I don't know how but I will find the way to put a demand.
