Been calling my phone for weeks and I have my number on the blocked/do not call list, why do I still receive these phone calls from unknown numbers when I have my cell phone on a blocked/do not call list?

first time

This number has called me starting at 1:55 pm and then each hour up until 10:00. Now has started again and it is 7am

I received a text asking to call this number saying I won a gift card, when I called it was very very rude people asking for my Visa card number telling me that if i signed up for Magazines then i would get 250$ in free gift cards when I wouldnt give them my information they proceded to say profanitys and hung up on me.

They called and left an ugly message on my cell phone. So I reported them to ftc.
