Phone rang twice, hung up. This happens often with this #

Do not call me again please

I can "hear" your frustration but you must realize that 800 notes is a user driven forum for discussing phone calls from unknown or suspicious callers.  You get that it's not likely that the caller will come to this web site, read your post, know who you are, know your number and stop calling you, right? Think about getting a call blocker or downloading a call blocking app for your cell.  You can control who has access to you via phone.  Here's the 800 notes forums on call blockers.  Take a look at it.  There's lots of good advice on the different types and brands.
