Who called from 2016047116

I get calls from this # with ID caller Fax global I don't answer anymore don't understand what they say

Caller ID said Fax Global.. left no message

I got a few calls from this number no message and no answer.

They keep calling here, because they called twice in 15 mins... Static voice so I hung up on them

caller id read fax global, don't know who they are so won't answer..must have this one on a blocked list so only rang once then bye-bye
