The 'so called person' that is talking is using a computer to talk English. The call is most likely coming from out of the country. I block their number and they have a new one 6 months later(in the same area code and prefix). If you answer the phone, ask them to say ABCD and 123. They can't and will hang up.
Another number blocked
Switch: LSANCARC5KD
Telco: WEST TELECOMM, INC.
What I wish for is that our telephone companies that we all subscribe to would allow 'us' the subscriber(s) to block an area code and the entire prefix!!!
