Constantly Calling

This company has called five times in the past couple days and don't say anything when I answer.  Now I answer the phone and set it by the tv, they usually hang up right away.  I used to get calls like this and when they ask for bank info I give them a differt name and number when they ask to check they have the right information.  This really makes them mad and we usually get into a yelling match and when I laugh at them they get even more mad and they will hang up and not bother me again.  I hope the Trump administration will finally but an end to this.
