Just another telemarketer. I almost answered this call as we know some people near Denver and thought it might be them, but 800Notes saved the day. Thank you 800Notes!
People you can put a block on your so phone for that particular phone number. Then if they call you, they will not be able to connect with you. You don't have to call them to get on the no call list, but you can do that if you want to you also. But just putting a block on them with your so phone is enough. Good luck with this! These sort of calls really are annoying, that's for sure!
