i dont know who he is.

at first, he would text me with some other girls' name and i ignored it but one day he called, i didn't pick up, he got my name from my voicemail greeting, left me an explicit vmail using my name, and has been spamming me ever since. So, when i found magicall's "pick and drop" option along with the sms blocking, i thought the problem was solved but somehow, even tho he texts the pic to my phone number like sms, it doesn't get ignored and i get notified of a new picmail.
how do i blacklist him?
