I don't answer calls where I do not know who is calling. They did not leave a message. But if you perform a MSN Reverse Number search it provides: (231) 887-1988 is a cell phone based in Manistee, MI
The registered service provider is Dobson Cellular Systems**.
Detailed listing information is not available.

Just added this # to my list.
I get satisfaction by immediatly adding these nonsense calls to my SELECTIVE CALL REJECTION list ... My phone company provides this feature with my phone service. Local #'s can be added manually ... long distance #'s can ONLY be added by following the prompts after getting the phone call. To access this feature thru my phone service I dial *60. If your phone company provides this feature, use it. Check in your phone directory under Products & Services.
Although I get nuisance calls from new #'s, I am slowly, but surely, fighting back, as I have seven #'s on my list and the frequency of calls has diminished.

Called at 12:24 EDT
We did not answer... NO message left on voice mail.

When I try calling the number I get a message saying the number I dialed is invalid.

I am sick of these calls.
You cannot get them to remove you from their call list. I think we get more calls since we joined the do not call list!~!@!!

The people are very rude!! Would not remove number from list, continued to tell me I sounded sexy on the phone, and "you don't know what I am doing on this end of the phone listening to you get so upset." Asked to speak to his supervisor and another man got on the phone, I told him I was sure the ohter man told him to blow me off, but I felt as though I was being sexually harrassed, he said you have no idea what it means to be harrassed, I said yes I do I work in a hospital. He said tell me what your job is that you are so harrassed. very rude sick men. I have reported them to my local police department
