They left no message, but have called numerous times.  It comes up on caller ID as "Unknown name."

Called and hung up before it could be answered.

I called them back.  This is "Donor Services".  They are a company that collects donations for various charities, including Associations of the Deaf of several states, National Guard Associations of various states, Salvation Army in several states, etc.

My caller id showed Rockwell, TX.  They said they were calling for "Children's Wish Foundation".  I asked if similar to "Make a Wish".  Their speal, they are just for children and they don't turn away children.  I said I give to Make a wish and wasn't interested.

Got one today that came up on caller ID as Texas call. No message left. Must not have been important.
