Who called from 7089654087

I have been receiving 3 or more calls per day from this number. Who is it?

no message - CID says Allstate Motor Club - caller now blocked

I have received 6 phone calls in the past week from this number. The people are NOT identifying themselves and I do not know who they are. They must stop this harrassment.

I also have received several calls from this number.  They never leave a message.  Peculiarly, one reverse directory says it is a cell phone but another says it is a landline.

Received a call from this number 5/27/2012. They did not leave a message and hung up before the answering machine could pick up.

Caller id states: ALZHEIMERSALERT
