We have been getting these calls for weeks. Usually no one is there and it hangs up.  Yesterday a guy actually asked for my husband by his full name.  I said my husband was not home could I help him.  He said it was a courtesy call for him and he would give me no information as to company.  I explained to him that my husband & I have been getting calls from this # for weeks and are getting very frustrated with it, could he give me a phone # to call as we don't want the calls anymore.  He said there was no phone # that he could give me,  I told him to remove us from the call list and he said he would.  Guess what,  we got another call this morning, no one was there!!!!!  My husband had called our local phone company and they said there was nothing they could do, but we could change our # if we wished...  Not likely we have had our # for years.  I can't believe that someone somewhere can not fix these problems, WITH ALL THE TECHNOLGY WE HAVE NOW!!!!
