Hi! I've been getting a ton of calls from this number, too. For the LG3, just put your finger on the number and hold it there for a couple seconds. From there, a drop down menu will pop up and you may select "REJECT CALL." Then, it will confirm that the number has been added to your 'call reject list.' Don't know if it blocks it entirely or sends it straight to voicemail, but either way, you won't have to deal with them anymore. :)
