Do you honestly think that these CRIMINALS are going to stop calling you? Really???
If anything, because you called them back it is more likely that your number will be sold to other criminals and/or used in their next criminal telemarketing campaign. Your number is now known as a "live" number. You have now called them twice - that speaks volumes about your intellect.
Criminals calling from WY. Over 2 years ago we blocked the entire 307 area code.
Our phones do not ring when ANY call comes from Wyoming - and that's just fine by us.
FYI, the 307 area code covers the entire state of WY.
