They just called. Download Mr.Number App. You can block them. I currently block about 30 numbers. They call and app hangs up on them. Reports them as Spam. What we can do now with smart phones now.
just emailed that company you posted and got back a almost right away reply that they will notify the rip off to stop calling and please let them know if they don't stop. also called the Colorado attorney generals office and filed a complaint
