When I picked up the phone, the guy on the other side politely explained that due to low demand for home phones, Verizon decided to cut phone bill by 40%.  But in order to do that, they need to verify some personal information.  The guy became very angry by raising voice when I said that I will call Verizon.  The guy was very demanding and insulting.  The person ended the call by stating '[***] Off'.  I don't usually get upset but that set me off.  I called the number and the automated service sounded like, 'Weslet Communications' and gave a 800 number if I wanted to put it on do not call list.  I am going to call Verizon as well.
