This is driving me nuts. I can't even get anybody on the phone to tell them to stop calling me! 5 times a day from 1pm all the way until 1030. I have a very demanding job and getting these calls while I'm with clients and in meetings is very frustrating and unappreciated! I live 5 hours AWAY from Michigan!
Look to see if you can get a free app for call blocking for your cell phone. There are a lot of them online and all you have to do is google you cell phone brand and call blocking app.
