Got a call from this number today, a Sunday, July 24, at 2:50 PM.  The caller id showed "Allen, TX".  I binged the number and it's on several spammer websites.  Blocked!!!

Sunday call, selling environmentally safe septic tank cleaning product.  Gave option to be removed from calling list.  I didn't answer.  Caller id listed as 4696568423.

These [***] called my home number on 9-3-16@7:15pm. Left no message on my machine! Glad I wasn't here to get it because I would have told them to take their septic tank chit and shove it! My wife wouldn't like that!
