Calls constantly and when you block one number they call right back with a different number

As soon as I said, I am on the Do Not Call List, he/she just hangup.

many have shared the same call since February 27, 2017 (Google the phone number and select 800-notes).

Caller ID showed as SPAM. Didn't answer just blocked the number

they were very rude and then hung up.

561-316-9458, 561-283-8414, 561-283-8405.

Called on three separate but similar numbers.

They call, let it ring once and hang up baiting you to call back.

They are calling my cell #

I do not recall the message or the company.

Woman with thick Indian accent said my computer had sent messages that it was downloading viruses.

When I asked the man to remove me from their call list, he replied "F&*K you, mother F*&$er". and hung up on me! How do I shut this guy down?
