Been getting this phone call for awhile and finally got around to blocking it on my sprint cell today.  If you have sprint you can easily block numbers.  Here's the link on how to do that https://community.sprint.com/baw/thread/62014
if you don't have sprint then google how to block numbers on your phone service provider

Press 1 now to get a business loan for any purpose.  The only qualification is that you've been in business for one year.  Personal credit does not matter.  Press 2 to be removed from our calling list (meaning, press 2 to acknowledge that you are stupid enough to press 2 and we will inundate you with more calls because you are one of those people who press 2).
