4 to 5 times daily. How can you block a caller?

I keep getting calls at home and on my cellphone. Just wish they would stop.

Called to ask if I had any interest in going back to school. Claimed to be a school adsvisor. Hung the phone up and added  number to call block.

I get calls from them non stop. I added myself to their do not call list but that doesn't work. You can't speak to anyone and if you answer no one is on the line. I have reported them over and over

I was going through my spam calls list and just saw over half a dozen missed calls from this number back in February, along with as couple of voice mails where she says my name in one. Creepy.

Not this number. But another kept calling about helping me with a mortgage. Sounds in the back ground like a warehouse instead of a busy office. So one morning he called and I was ready for him. I blew a whistle into the phone. Haven't heard from him since.

I keep getting calls from this number, it is constant, like 4 calls within 1hr. I don't know who it is, I just want it to stop.
