I have received 8 calls so far today from phone number 0000000000, and when i have answered the call, someone tells me that i've won $100 gift bundle and they get very rude when i ask who they are and what company they are calling from. It's very frustrating.
I don't think you can block those numbers with the free blocking option, but you can block them with Usage Controls, which will allow you to block up to 20 numbers, including Restricted numbers, 411, and "000-000-0000." It costs $4.99 per line. It has other features as well.:
