Find out if your carrier has a block feature. I have verizon, they do and I got so many calls from them, I added them to my block. I can only add 5 at a time and I think it works for only 90 days. Then you have to add them again if they start up again. Give it a try.

We got several calls from this number.

This number continues to call me throughout the day, but when I call back I get a busy signal. I want this stopped.

I have received several calls from this number on my cell and can never answer in time to tell them to stop calling.  When I try to call back I get a busy signal.
