You can stop it by 1. signing up for the do not call registry and 2. by adding to your reject list if you are receiving the calls on a cellular.I received a call today as well. I did not answer and they left no voicemail.
tcould be another diabetes company calling me but I do not have diabetes. is number keeps calling me and whether I answer or not it hangs up as soon as I answer. I have called 6 times in the past hour and a half. And hung up.
