Millions Call

I am on the 'Do Not Call' list.  I'm not sure how many times these people have called but it's more than once.  They do not leave a message.  On my caller i.d. there is no name listed.  Is anyone else receiving calls from this telemarketer?I'm beginning to think it doesn't do any good to go on the 'Do Not Call' list because I've had problems with other companies.

Anonymous caller with no message

The person never speaks, and you can hear them moving and they hang up when you speak.

We are asked to get back to this no. & we just like to recognise who was doing this before we make the ring when we make.

Has rang two times we picked up 1st ring some thing about signing up for online course.

Spam Risk

Received a call from this number, it was a female that stated I had called her, although there was no number called from my phone to that number. Not sure if she redialed or just dialed a random number.

They keep calling me relentlessly

They stated they are coming to my job unless they I pay them.    THey stated that I owe money.

Keeps calling back to back
