I get at least 2 calls a week from this number which is a fax. It goes into the cell and uses my minutes and wastes my time. I have filed a complaint with the do not call list. This has been going on for months. Unfortunately I can't block it unless I want to pay a monthly fee with my cell company which I don't feel I need to do just because of this one company.  They also use another fax number which is 310-9144129. It is extremely frustrating.
