I received these calls today from both numbers- I also work 3rd shift. The calls came every minute or so, whether I ignored/hung up on them or not. I finally had to turn off my phone and the calls stopped.
Over 100 unwanted fax calls from two numbers in less than 30 days. 469-324-0109 and 312-205-0109
Direct line to VENALI INC is (786)552-1900 (customer support press "2")
Call them and tell them what is going on. May work, may not, but will let them know they have lots of complaints. Person I contacted said they were a service company that sends faxes for other companies. Did say he would contact other company to have my number (which is a private line and not for faxes), removed.
I'll post results here in one week.
